Answer:
An Odd number
Step-by-step explanation:
An odd number can not be divide by two and stay whole or every odd number ends with 1,3,5,7,or 9
Answer:3/4
Step-by-step explanation:
Multiply 1/6 by 2 to get 2/12 and then add that to 7/12 and get 9/12
If you simplify that you end up with 3/4
Answer:
20.6
Step-by-step explanation:
Use the trig function Cosine to find the length of the ramp. The cosine function is defined as the ratio adjacent side over hypotenuse. The base 20 is the adjacent side to the angle 14 while the length of the ramp is the hypotenuse. Using the function we write, cos 14 = 20 / x. Solve for x.
Cos 14 = 20 / x
x*Cos 14 = 20
x = 20 / cos 14
x = 20.6
Assuming the dice rolls are independent, the probability of getting doubles is
. (That is, there are 6 ways of getting doubles, and the probability of getting a given face is 1/6.)
So the event of getting doubles in a set number of
trials is binomially distributed with
(and so
).
You're given that
. If
is a random variable representing the number of doubles obtained in
trials, then the probability of getting
doubles is given by the PMF,
