Since it's a sample size, we use x, as the mean and s= standard deviation
_
Given: x =27, s = 2 and total sample = 32.
Probability that a recruit is at least 31 years old?
Let's calculate the Z score :
_
X - x 31 - 27
Z = ----------- → Z = -------- → Z = 2 (now look up in the Z score table,
s 2
Area (Z=2) =0.9772 , but Z ≥ 2 (at least) , then :
Area (Z≥2) = Area (Z≤ - 2) = 0.0228
P(≥31)= 0.0228
Probability of rolling a 3 is 1/6
200 x 1/6 = 200/6
Expectation = 200/6 ie 33.333, 33 to the nearest whole number
So you would expect to roll a three 33 times

Don't get nervous u will do Great !!!
Answer:
Step-by-step explanation:
30 - [(9 X 2) - (3 X 4)]
30 - [ 18 - 12 ]
30 - 18 + 12
= 42 - 18
= <u><em>24 </em></u>
Hope this helps
plz mark as brainliest!!!!!!
