Step-by-step explanation:

From the question,

orange jelly beans= 7

Cherry jelly beans =9

Lemon jelly beans = 3

Licorice jelly beans = 15

Blueberry jelly beans = 6

Total jelly beans = 40

The probability of choosing the first cherry jelly beans will be = 9/40

After the first one is chosen, there'll be 8 cherry jelly beans and total of 39 left. The probability of choosing the second one will be = 8/39

Find the indicated term of the given geometric sequence a1=-20, r=11, n=12
Sphinxa [80]

The first term of this sequence is -20, and the common ratio is 11. Thus, the formula for the nth term is

a(n) = a(1)*(11)^(n-1), or (-20)*(11)^(n-1).

Thus, the 12th term is

a(12) = (-20)*(11)^(12-1) = -20(11)^11 = -20(2.85 times 10 to the 11th power.

or ... -5.71 times 10 to the 12th power.
