If the number of orders at a production center this month is a Geom(0.7) random variable, find the probability that we'll have at most 3 orders.

0.973

Step-by-step explanation:

The probability mass function of geometric distribution is

, p= probability of success on a trial.

As per given, we have

p=0.7

The probability that we'll have at most 3 orders

hence, the required probability = 0.973

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

the answer is:

mean: 6

mad: 2.14
