Answer:
Here’s the answer,
Step-by-step explanation:
There are 392 seats in both rooms.
The probability is 0.336.
To solve this, we need Binomial Probability equation for Repeated Trials.
P = nCr (p)^r (q)^(n-r)
where P = probability (unknown)
n = number of trials (8)
r = number of successes (1)
p = probability of success (.20)
q = probability of failure (0.80)
P = 8C1 (.20)^1 (.80)^7
= 0.336
24 calculator 8 pens so 32 all together he had 16 dollars left because the fraction is 32/48 equals 2/3
Answer:
0.6341 = 63.41% probability that his commute today took more than 35 minutes
Step-by-step explanation:
Randomly distributed = Uniform distribution.
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:
Randomly distributed with a minimum of 20 minutes, a maximum of 61 minutes.
This means that .
What is the probability that his commute today took more than 35 minutes?
0.6341 = 63.41% probability that his commute today took more than 35 minutes
