Answer:
26.17%
Step-by-step explanation:
P(Grey) = 1/4
P(Grey at least 2 times in 4) = 1 - P(no Grey in 4) - P(1 Grey in 4)
P(no Grey in 4) = 4C0 * 3/4 * 3/4 * 3/4 * 3/4 = 81/256
P(1 Grey in 4) = 4C1 * 1/4 * 3/4 * 3/4 * 3/4 = 27/64
P(Grey at least 2 times in 4) = 1 - 81/256 - 27/64 = (256-81-108)/256=67/256=26.17%
Here is an example of how to do this.. sense $4 x 6 just continue the graph i have already started
Answer: There are 90 different schedules are possible for Molly Kay.
Step-by-step explanation:
Since we have given that
Three time scheduled at 8:00, 10:00, 11:00.
Number of courses offer at 8:00 = 5
Number of courses offer at 10:00 = 9
Number of courses offer at 11:00 = 2
So, the number of different schedules are possible for Molly Kay is given by

Hence, there are 90 different schedules are possible for Molly Kay.
Answer:
y = 52.02
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj/ hyp
cos y = 8/13
Take the inverse cos of each side
cos ^-1 cos y = cos ^-1 ( 8/13)
y = cos ^-1 ( 8/13)
y = 52.02012756
To the nearest hundredth
y = 52.02
