Step-by-step explanation:
In basic probability theory, AND means MULTIPLICATION and OR means ADDITION.
<em>We want to find probability of grey pair of shorts </em>AND<em> grey T-Shirt. So we need to </em><em>multiply</em><em> the individual probabilities.</em>
P(grey shorts) = (total 4 colors and 1 grey)
P(grey tshirt) = (total 3 colors and 1 grey)
P(grey shorts AND grey tshirt) =
Using the normal distribution, it is found that the correct option is:
- D. 1; 100
In a <em>normal distribution</em> with mean and standard deviation
, the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
In this problem:
- The mean on the Wechsler Scale is of 100, hence
.
- The standard deviation is of 17, hence
.
- Brianna had an score of 117, hence
Then:
Hence, the option d is correct.
