The random selection of a blue marble is an illustration of probability
You should expected to pull a blue marble 10 times
<h3>How to determine the expected blue marble?</h3>
The given parameters are:
Blue = 16
Red = 12
Green = 12
The total number of marbles is:
Total = 16 + 12 + 12
So we have:
Total = 40
The probability of selecting a blue marble is:
When 25 marbles are selected, the expected number of blue is:
So, we have:
Hence, the expected number of blue marbles is 10

Answer:
Step-by-step explanation:
Simple interest is
I=Prt
I=11500(0.10)(60/360)
I=$191.67
Given:
Women only gym:
60% married women
75% of the married women exercise in the morning
30% of the single women exercise in the morning
60% married women + 40% single women = total women members
60% married
75% exercise in the morning
25% exercise in the afternoon or evening
40% single
30% exercise in the morning
70% exercise in the afternoon or evening
Exercise in the morning
married: 60% x 75% = 45%
single: 40% x 30% = 12%
<span>
B) Yes. P(married and exercise in the morning) = P(married)·P(exercise in the morning) = 45% </span>
