Use a calculator to find the value of the acute 0 to the nearest degree Tan0=7.7336

In degree mode, the answer is around 83. You use the inverse tangent button on the calculator to get rid of the tangent and find what theta is (make sure your calculator is in degree mode)

Two dice are rolled. What is the probability that the sum of numbers rolled is either 5 or 12?

Maksim231197 [3]

ANSWER:

The probability that sum of numbers rolled is either 5 or 12 is $\frac{5}{36}$

SOLUTION:

Given, Two dice are rolled.

We have to find what is the probability that the sum of numbers rolled is either 5 or 12

We know that, probability of an event = $\frac{\text { favourable outcomes }}{\text { total outcomes }}$

Now, total outcomes for two dices = 6 for 1st dice x 6 for 2nd dice = 6 x 6 = 36.

Now, favourable outcomes = sum is 5 + sum is 12

= 4[(1,4), (2,3), (3, 2), (4, 1)] + 1[(6,6)]

= 5 total favourable outcomes.

Now, probability = 5/36

Hence, the probability that sum is either 5 or 12 is 5/36.

CAN SOMEONE HELP ME ON THIS PLEASE AND THANK YOU.

Answer/Step-by-step explanation:

2/5 + 1/3

5 times 3 is 15, so 2*3 and 1*5

6/15 + 5/15

6+5 = 11, and 11/15 cannot be simplified so:

11/15
