Answer: 0.14155776
Step-by-step explanation:
Given : The proportion of workers employed by the university belong to the workers' union=0.96
Let x be a binomial variable that represents that worker belongs to the workers' union.
Sample size : n= 4
[Binomial probability formula : P(X=x)=^nC_x(p)^x(1-p)^{n-x}]
Hence, the probability that exactly 3 of the workers interviewed are union members
Answer:
Step-by-step explanation:
Favorable outcomes (sum is a multiple of 3): (1,2) , (1, 5), (1,8), (2,1) , (2,4), (2,7) , (3, 3), (3, 6), (4, 2), (4, 5) , (4, 8), (5,1), (5, 4), (5, 7), (6,3), (6, 6).
Number of favorable outcomes (sum is a multiple of 3): 16
Total outcomes = Total outcomes of 6-sided die x Total outcomes of 8-sided die=6 × 8 = 48
Then , the probability of getting numbers whose sum is a multiple of 3:
Hence, the required probability =
Answer:
<em>% is the decrease.</em>
<em />
Step-by-step explanation:
<em>To figure out the percentage decrease, you would first subtract the two numbers. </em>

Answer:
Step-by-step explanation:
Given that,
The dimensions of a rectangular block = 4 cm x 2 cm x 1.5 cm
Mass, m = 93.6 g
We need to find the density of steel. We know that the density of an object is equal to the mass divided by volume. So,
So, the density of the steel is .
