a fair (6 sided) die is rolled TWO times. What is the probability that the first die is a 2 or the second die is a prime

alexdok [17]

Answer:

The probability that the first die is a 2 or the second die is a prime = 1/12

Step-by-step explanation:

It is given that,a fair (6 sided) die is rolled TWO times.

The sample space for rolling 2 dies

(1, 1), (1, 2) .......... (1,6)

(2,1) ..........................

(6, 1) ..........................(6, 6)

There are total of 6^2 = 36 sample space

<u>To find the probability</u>

The prime numbers from 1 to 6 are 2, 3 and 5

the possible outcomes are(2,1), (2, 3) and (2, 5)

The probability that the first die is a 2 or the second die is a prime = 3/36 = 1/12

Jennifer places $500 into a savings account that is paying 1.5% annual interest. The interest is compounded monthly. How much mo

Anna11 [10]

Answer:

$522.99

Step-by-step explanation:

$FV = P (1 + \frac{r}{n} )^n^t$

Fv = total amount plus interest over the given period of time

P = Principal amount deposited i.e $500

r = interest given 1.5% i.e 0.015

n = period of time the principal remains deposited. In this case annually i.e 12 months

$FV = 500 ( 1 + \frac{0.015}{12} ) ^1^2^X^3$

$FV = 500 ( 1.04599)$

FV = $522.99
