Ques:- There are 6 couples (12 people). 4 people are selected at random. What is the probability that exactly one couple will be selected ?
Recent Answer : Added by An On 2022-09-15 16:37:14:
Prob(choosing two people who are a couple from 6 couples) = 1/6
We have 5 couple left (10 people)
Prob(choosing a person A from 10 people) = 1/10
Prob(choosing 1 person who is not a couple of A) = 1/8
Prob(choosing 4 people that has exactly one couple) = 1/6*1/8*1/10 = 0.0021

Ques:- A county cricket team has won 10 matches and lost 4. If these matches represent 70% of the matches to be played, how many more matches should the team win so as to have a record of 75% wins?
Recent Answer : Added by DK BOSS On 2021-07-17 06:18:54:
Let the total number of matches to played in the tournament be ‘x’.
Given that A county cricket team has won 10 matches and lost 4.
That means total number of matches played = 14.
So,
= > 70% of x = 14
= > (70/100) * x = 14
= > 70x = 1400
= > x = 20.
So, the number of matches to be played = 20.
They have a record of exactly 75% wins = 20 * 75/100
= > 15.
Therefore, the number of matches should the team win = 15 – 10 = 5.
Hope this helps!
