If Z is the standard normal variable, then what is the P(Z < -1.23) ?

1 answer:

8 0

Step-by-step explanation:

If Z is following a standard normal distribution, then P(Z>0) would be 0.5. Standard normal distributions are symmetrical with a mean of 0, so half of the distribution will be above 0 (i.e., 0.5).

kogti [31]

Answer:

4*5*7=140 ways

Step-by-step explanation:

First he has to decide on a pair of pants and he has 4 different choices.

For each of those choices he has a choice of 7 different shirts, so that gives him 4 times 7 = 28 different pant/shirt combinations. (I hope none of the pants are striped and none of the shirts have polka-dots).

For each those 28 possibilities, he has 5 different ties he could select, so altogether he has 28 times 5 = 140 different outfits, and some of them may be acceptable to wear in public.

It is simply , 4*5*7=140 ways.
