Answer 1

0.2164 is probability that exactly 4 of the couples said that they paid for their honeymoon.

What are examples and probability?

• It is based on the probabilities that something could happen.
• The logic underpinning probability serves as the foundation for theoretical probability.
• The theoretical likelihood of receiving a head, for instance, is 12 when a coin is tossed.

If x = no of married couples out of 5 who paid for their honeymoon .

then X ~ ( 5 , 0.56 )

P (X = 4 ) =  5C4( 0.56 )⁴ ( 0.44)¹

                = 0.2164
