Question

the probability of 3 students A,B,C solving a problem in statistics are 1/2,1/3,1/4.A problem is given to all students .Discuss the probability that no one will solve the problem only one will solve the problem at least one will solve the problem
​

Answer 1

Step-by-step explanation:

P (A solving the question)=21

P(B solving the question)=31

P(C solving the question)=41

i)P (only one at then solves the question)=P(only A solves)+(only B solves)+(P only C solves)

=P(A∩B0∩C0)+P(A0∩B∩C0)+P(A0∩B0∩C)

=21×32×43+21×31×43+21×32×41

=41+81+12
