So first you need your denominators to be the same so you can multiply. They share a common denominator of 24. 2/3 equals 16/24 and 2/8 equals 9/24. So now you need to turn your fractions into mixed numbers and multiply. Which equals 2112/576. That # is way to big so then you simplify and get 11/3. so now you have 5 and 1/6 divided by 11/3. So now just flip the second fraction multiply it by its reciprocal. 31/6 X 3/11=___. So your final answer is 1 and 9/22
It should be answer B. With 0.0321 there is a zero both before and after the decimal, while answer A only has one before the decimal.
Answer:
P( X ₙ ≤ 3) = e⁻³ [1+5+5²/2!+5²/3!]
Step-by-step explanation:
There are different way to solve it
Number of men and women entering are two separate Poisson random variable , with total number of people entering with rates being the sum of two. Poisson distributed with λ M
and for women
Poisson distributed with λ W
If we assume that men and women come in same rate then
λ M = λ W
But from the problem we see that
λ M + λ W = 10
M
≈Poisson{x;5}
P( X ₙ ≤ 3) = e⁻³ [1+5+5²/2!+5²/3!]
