The chess club has 28 members that are divided into 2 groups. The difference between the number of people in the first group is equal to 3 more than one half the average of the two groups. How many people are in the larger group?

Honest Truth: u I really don't know im sorry. You know what let me just stop I don't know why im here if I don't know the answer

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
