<span>On the first roll, the probability of rolling a 2 is 1/6.
On the second roll the probability of rolling a 3 is also 1/6, and the probability of rolling a 4 on the third roll is, you guessed it, 1/6.
Therefore the required probability is given by:
1/6 x 1/6 x 1/6 = 1/216</span>
Answer:0,0025
Step-by-step explanation:
P(select a married couple) = P(person selected from Company A is one of the 50 with spouse at Company B) x P(person selected from Company B spouse of person already selected from Company A)
Now you can substitute the respective probabilities .

Answer:
9.750
Step-by-step explanation:
formula for average rate of change is ;
f(b)- f(a)/b- a
here a = 1 and b = 2.5
f(b) = (2.5)^3 + 2 = 17.625
f(a) = 1^3+ 2 = 3
using the formula above, we have it that
(17.625-3)/2.5-1 = 9.750
