Answer:
0.9401 is the required probability.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 41
Standard Deviation, σ = 9
We are given that the distribution of number of milligrams of porphyrin is a bell shaped distribution that is a normal distribution.
Formula:
P(x is less than 55)
Calculation the value from standard normal z table, we have,
0.9401 is the probability that x is less than 55.
Answer:
3024
Step-by-step explanation:
Each chosen member (out of 9 members) will occupy a different position
out of these four (president , vice-president , secretary , treasurer).
So, here we have to calculate the <u>Number of Permutations</u> of 9 members Taken 4 at a Time :
= 9P4
= 9 × 8 × 7 × 6
= 3024
