Answer:
Step-by-step explanation:
Total number of students =100
Number who bought pop corn = 62
Number who bought drinks = 47
Number who bought both =38
Hence number who did not purchase anything = 100-(62+47-38)
=29
Prob that students buys a drink = 47/100 = 0.47
PROB THAT THE student buys a drink/he purchsaed pop corn
= Number for both/number of pop corn
=38/62 =0.613
P(buying pop corn) = 0.62 and P(drink) = 0.47
Product of these = 0.62*0.37=0.2356
Thus we find product is not equal to Prob of purchsing both
Hence cannot be independent
The event "P and Q" is a compound event in the probability, and the true statement about the probability is P(P and Q) = 1/9
<h3>How to determine the true statement?</h3>
The probabilities are given as:
P(P) = 1/6
P(Q) = 2/3
The probability of the event P and Q is calculated using:
P(P and Q) = P(P) * P(Q)
This gives
P(P and Q) = 1/6 * 2/3
Evaluate the product
P(P and Q) = 1/9
Hence, the true statement about the probability is P(P and Q) = 1/9

Sam would have to get a 97 on his next test in order to maintain his average score at an 85. This is because if you add up 63, 84, 96, and 97 you get 340. When you divide 340 by the 4 test scores you get an average of exactly 85
<span>First, we must calculate the amount that will be available after two years. This is given by:
Amount = initial amount * (1 + interest rate)^time
Amount = 1500 * (1 + 0.05)^2
Amount = $1,653.75
Therefore, the only items you can buy using this amount are the electronics worth $1,650</span>
