Answer:
Step-by-step explanation:
This is a binomial probability distribution because there are only 2 possible outcomes. It is either a randomly selected student grabs a packet before being seated or the student sits first before grabbing a packet. The probability of success, p in this scenario would be that a randomly selected student sits first before grabbing a packet. Therefore,
p = 1 - 0.81 = 0.91
n = 9 students
x = number of success = 3
The probability that exactly two students sit first before grabbing a packet, P(x = 2) would be determined from the binomial probability distribution calculator. Therefore,
P(x = 2) = 0.297
Answer:I think it's 3 7.75/20 hours
Step-by-step explanation:
Multiply 2/15 by 20 (2x20 and 15x20)
Then 13/20 by 15 (13x15 and 20x15)
Subtract (195/300 - 40/300)
And you get 155/300
Then divide by 20 because dividing by 15 gives you 10.333333
So divide 155/300 by 20 (155÷20 and 300÷20)
And you get 7.75/20
Finally subtract the 2 hours from 5 hours and get 3 hours
Your answer is 3 7.75 hours
