5(R + 2) - 6....distribute the 5 thru the parenthesis
5R + 10 - 6 =
5R + 4 <==
To be honest i really dont know but if i have it i would tell u
Answer:
it has a 20% chance to land on either and 10% chance to land on each one by itself
Step-by-step explanation:
Answer:
a) Mean(x) = 0.40
b) Variance(x) = 0.24
Step-by-step explanation:
From the information given, the process is Bernoulli process, since the team can run or pass the ball into the end zone to score two points only. We are not told the number of times. Thus, <em>n </em>is unknown. That is, we are not told how many times the team successfully pass the ball into the end zone.
By Bernoulli process, the mean and variance are given as follow:
Mean = p
Variance = pq. This is the same as p(1-p)
Where p is the probability that this play is successful and q is the probability that this play is not successful.
