Answer:
Expected number of guests is 100.4.
Step-by-step explanation:
It is given that there are 161 guest if there is a heavy snow fall.
Also, the probability for a heavy snow fall is 0.40.
Therefore, P(X = 161) =0.4.
It is also given that there are 60 guests if there is a light snow fall.
The probability for a light snow fall is 1 - 0.4 = 0.6.
Therefore, P(X = 60) = 0.6.
Expected number of guests = (161)P(X = 161) + (60)P(X = 60)
= 161(0.4) + 60(0.6)
= 64.4 + 36
= 100.4
Answer
Sorry! number 12 is 2
Step-by-step explanation:
If you would like to solve the equation x/3 = x/2 - 2 for x, you can do this using the following steps:
<span>x/3 = x/2 - 2 /*6
</span>2x = 3x - 2 * 6
2x = 3x - 12
2x - 3x = -12
-x = -12
x = 12
The correct result would be x = 12.
