The <u>correct answer</u> is:
16/45.
Explanation:
We want the probability that a student's eye color is blue if they made an A in physics. This means we look at the column for students with an A.
There are 32 students with blue eyes in the A column.
This is out of 32+58=90 students that made an A.
This makes the probability 32/90, which simplifies to 16/45.
Answer:
i believe the answer is C
Step-by-step explanation:
Answer:
Prob ( 41 <= X <= 77) =
Prob ( (41-59)/9 <= Z <= (77-59)/9 ) = <--- changes to z scores
Prob ( -18/9 <= Z <= 18/9 ) =
Prob ( -2 <= Z <= 2) =
Prob ( z<=2) - Prob(Z<=-2) = <--- by property of the normal bell curve
= 0.9772 - 0.0228 <--- per the normal distribution table
= 0.9544
