If the probability that a person is not a swimmer is 0.3, then the probability that out of 5 persons 4 are swimmers is

If the probability that a person is not a swimmer is 0.3, then the probability that out of 5 persons 4 are swimmers is

The probability that a student is not a swimmer is 1/5 . Then the probability that out of five students, four are swimmers is (A) ^5C_4""(4/5)^4""1/5 (B) (4/5)^4""1/5 (C) ^5C_1 1/5(4/5)^4 (D) None of these

The probability that a student is not a swimmer is 1/5 . Then the probability that out of five students, four are swimmers is (A) .^(5)C_(4)(4/5)^(4)1/5 (B) (4/5)^41/5 (C) ^5C_1 1/5(4/5)^4 (D) None of these

The probability that a student is not a swimmer is 1/5. Then find the probability that out of 5 students exactly 4 are swimmer.

The probability that a student is not swimmer is 1//4 . Then the probability that out of five students atleast four are swimmers is
