Answer: 2.28%
Step-by-step explanation:
μ = 71.8
σ = 3.4
X < 65
P(X < 65) = P (Z < 65 - 71.8/3.4) = P (Z < -2)
According to the table for the normal distribution attached, it will give us
P (z < Z < 0), this way, to find the P(Z < z), we need to do 0.5 - P:
0.5 - P(-2 < Z < 0) = 0.5 - 0.4772 = 0.0228
In percentage: 0.0228*100 = 2.28%

Answer:
Getting a multiple of 5 is the least likely outcome.
Step-by-step explanation:
We spin a spinner that has 8 equal-sized sections numbered 1 - 8.
We have to find which is the least likely to occur.
The number is even when outcomes are 2,4,6 or 8.
Number of outcomes = 4
If the number is less than 3, the number of possible outcomes are 2 that is 1 and 2.
If the number is greater than 3 , number of possible outcomes is 5 which are 4,5,6,7 and 8.
If the number is a multiple of 5, only 1 outcome is there which is 5 itself.
Hence getting a multiple of 5 is the least likely outcome.
