The probability that a student passes in a physics test is `2/3` and the probability that he passes both the physics and English test is `14/45`. If the probability that he passes at least one test is `4/5`, find the probability that the student passes exactly one of the two tests

The probability that a student passes in a physics test is 2/3 and the probability that he passes both the physics and English test is 14/45 . If the probability that he passes at least one test is 4/5 , find the probability that the student passes English test.

The probability that a student passes in a physics test is 2/3 and the probability that he passes both the physics and English test is 14/45 . If the probability that he passes at least one test is 4/5 , find the probability that the student passes neither the Physics test nor the English test.

The probability that a student passes in a physics test is 2/3 and the probability that he passes both the physics and English test is 14/45. If the probability that he passes at least one test is 4/5, find the probability that the student does't pass the physics test

Probability that Ram passsed in mathematics is 2/3 and the probability that he passed in English is 4/9.If the probability of passing in both subject is 1/4,then what is the probability that Ram will pass in atleast one of these subjects?

Two student A and B appeared in an examination. The probability that A passes the examination is 0.25 and that B passes is 0.45. Also the probability that both will pass is 0.1. Find the probability that: Both will not pass.

Two student A and B appeared in an examination. The probability that A passes the examination is 0.25 and that B passes is 0.45. Also the probability that both will pass is 0.1. Find the probability that: Only one of them will pass.

The probability that a contractor will get a plumbing contract is 2/3 and the probability that he will not get an electric contract is 5/9. The probability that he will get at least one contract is 4/5.suppose A is the event that ther contract will get plumbing contract and B is the event that the contractor will get electric contract.P(A)=..........., P(B)=..............., P(AcupB) =...............

The probability that a contractor will get a plumbing contract is 2/3 and the probability that he will not get an electric contract is 5/9 . The probability that he will get at least one contract is 4/5 .suppose A is the event that the contractor will get plumbing contract and B is the event that the contractor will get electric contract. using addition theorem of probability find the probability that the contractor will get both the contracts.

The probability that a contractor will get a plumbing contract is 2/3 and the probability that he will not get an electric contract is 5/9. The probability that he will get at least one contract is 4/5.suppose A is the event that ther contract will get plumbing contract and B is the event that the contractor will get electric contract.Also find the probability that the contractor will get both the contracts.

In a simultaneous toss of two coins,find the probability of getting:exactly one head.
