Answer: 3
Step-by-step explanation:
Mean simply means average. To calculate mean,we add together all the numbers given and divide them by the amount of numbers.
The Mean here will be:
= [8 +(-10) + 7 + 10 + (-3) + 6]/6
=18/6
= 3
The mean is 3
Answer:
The probability is 0.000000207176
Step-by-step explanation:
In this question, we are asked to calculate the probability that if 6 cards are selected from a deck of cards, we will be having 4 kings and 2 queens.
Before we answer, we should understand that in a deck of cards, there are 4 queens and 4 kings. The probability of selecting a king is the same as the probability of selecting a queen which is 4/52 = 1/13
Okay now we want to find the probability of the six cards being 4 kings and 2 queens. Since the probabilities are equal, we proceed to calculate at the same time.
That would be (1/13)^6 = 0.000000207176
The probability of selecting 4 kings and 2 queens is 0.000000207176
