Question

every time Brietta goes to the mall, she has a 0.6 chance of forgetting where she parked her car. if she goes to the mall 5 times this month, what is the probability that she will forget where she parked. a.) exactly 2 times. b.) at least 2 times. c.) less than 3 times

Answer 1

Probability of forgetting the parking location of the car=p=0.6.

Let the random variable X is representing the number of times she forgot the parking location out of 5 visits to the mall. That is The random variable X is distributed as Binomial with n=5 and probability of success p=0.6.

The distribution of X is given by,

a) what is the probability that she will forget where she parked exactly 2 times.

ANS:- =0.2306

b) at least 2 times

ANS:- The required probability is ,

c) less than 3 times

ANS:- The required probability is
