To get the probability of two individual events both occurring,
you have to multiply the probabilities of their individual events occurring. Therefore
in this problem, the probability that a student selected at random will pass
both French 101 and French 102 is 0.683 (.75 x .91). The answer is already
rounded to three decimal places.
Answer:
the answer is not on here but it is 5 other than that it might be 5/1.
so D
and B.
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
This is because of the distributive property.
The outside number is multiplied by each inside number.
So, if it's 9(5x+8y), then do 9*5x which is 45x and 9*8y which is 72y.
2.5 and 3.5 are two standard deviations from the mean, since 2.5 = 3 - 2(0.25) and 3.5 = 3+2(0.25).
The empirical (68-95-99.7) rule says that approximately 95% of a normal distribution falls within two standard deviations of the mean.
