Apicnic was arranged for the members of a club. the organizer started calling all the members to find how many members would be taking part in the picnic. she could not contact 20% of them. of the remaining members, 15% did not wish to take part and the rest wanted more time to decide. finally, 80% of those who wanted more time to decide ended up going to the picnic. if a member is picked up at random, the probability that he or she needed more time to decide and finally did not attend the picnic is ? %, and the probability that he or she was contacted but did not attend the picnic is ? %

The probability that he or she needed more time to decide and finally did not attend the picnic is :  13.6%

The probability that he or she was contacted but did not attend the picnic is : 25.6%

Let P denote the probability of an event.

Now, it is given that:

→ At last 80% of 85% of 80% decided to go for picnic.

→ while 20% of 85% of 80% decided not to go to the picnic.

This means that:

The probability that he or she needed more time to decide and finally did not attend the picnic is :  (0.20×0.85×0.80)×100=13.6%

The probability that he or she was contacted but did not attend the picnic is :  [(0.80×0.85×0.20)+(0.80×0.15)]×100=25.6%
