Answer:
mean=14, variance=9.1
Step-by-step explanation:
for binomial distribution
n=number of outcomes
p=probability of succcess
q=probability of faliure
p+q=1
any probability given is always 'p'
mean=np
n=40
p=0.35
mean=40*0.35
mean=14
variance=npq
p+q=1
q=1-p
q=1-0.35
q=0.65
variance=40*0.35*0.65
variance=9.1
