Question

If the probability of success of an experiment is 0.4 what is the probability of failure?​

Answer 1

Answer:

Correct option is

B

0.784

p=0.4

q=1−0.4=0.6

Hence the required probability is

=3(0.4)(0.36)+3(0.16(0.6))+(0.064)

=0.432+0.288+0.064

=0.784

Answer 2

Answer:

let the probability of failure be x

0.4+x=1

x=1-0.4

x=0.6
