Question

a student trying to seek admission in either of two college. the probability that he is admitted in first college is 3/5 and that is second college is 1/3. find the probability that he is admitted at least one of the college​

Answer 1

Answer:

probability of getting admitted in atleast one college= 11÷15

Step-by-step explanation:

Probability of getting admitted in atleast one college=1-

probability of not getting admitted in both the colleges

Probability of not getting admitted in first college= 1-(3÷5)

                                                                                  =2÷5

Probability of not getting admitted in second college = 1-(1÷3)

                                                                                       =2÷3

Probability of not getting admitted in both the college = (2÷5)×(2÷3)

                                                                                          =4÷15

Therefore probability of getting admitted in atleast one college= 1-(4÷15)

                                                                                                         =11÷15
