A set of art exam scores are normally distributed with a mean of
scZoUnD [109]

Answer:

The percentage of people that scored less than Calvin is 38.21 %

Step-by-step explanation:

In this question, we are concerned with calculating the percentage of exam scores lesser than what Calvin scores.

To calculate this, we first need to calculate the standard score or the z-score of Calvin result.

Mathematically;

z = (x - mean)/SD

from the question, x = 78, mean = 81 and SD = 10

Substituting this, we have

z = (78 -81)/10 = -3/10 = -0.3

So we proceed to calculate the probability.

P(x < 78) or P(z < -0.3)

We make use of the standard table to get this probability

P(z< - 0.3) = 0.38209

In percentage, this is same as 38.209% or more simply 38.21%

cynara has a bag of red, blue, and black pens. She randomly selects a pen, records the color, and puts it back in the bag, She d
Katyanochek1 [597]

Divide the number of times she picked a color by the total times she picked a pen:

Red = 6/30 reduces to 1/5

Blue = 10/30 reduces to 1/3

Black = 14/30 reduces to 7/15

The probability of picking a blue pen , then a red pen is found by multiplying the two possibilities together:

1/3 x 1/5 = 1/15

There is a 1/15 probability.
