Numberse are selected at random, one at a time, from the two-digit numbers 00,01,02,….99 with replacement. An event E occurs if and only if the product of the two digits of a selected number is 18. If four numbers are selected, find probability that the event E occurs at least 3 times.

Numbers are selected at random, one at a time , from the two digit numbers 00,01,02,……99 with replacement. An event E occurs if and only if the product of the two digits of a selected number is 18 . If four numbers are selected , the probability that the event E occurs at least 3 times is .

Numbers are selected at randm, one at time, from the two-digit numbers 00,01,02…,99 with replacement. An event E occurs if the only product of the two digits of a selected number is 18. If four members are selected, find the probability that the event E occurs at least 3 times.

Numbers are selected at random,one at a time,from the with replacement.event E occurs if and only if the product of the two digits of a selected number is 18. If four numbers are selected,find probability that the event E occurs at least 3xx.

The sum of the digits of a 2-digit number is 10. A number is selected at random. Find the probability of the chosen number to be divisible by 3.

Out of one digit prime numbers, one number is selected at random. The probability of selecting an even number is:

The sum of the digits of a two digit number is 10. If 18 is subtracted from the number, digits are reversed. Find the numbers.

From the set of numbers {1,2,3,...,10} , 4 numbers are selected at random. The probability that at least 2 of the selected numbers are consecutive is

From the set of numbers {1,2,3,...,10} , 4 numbers are selected at random. The probability that at least 2 of the selected numbers are consecutive is

Let n be the number of trials that an event E occurred and m be the total number of trials, then find the probability of the event E.
