Probability is found by putting the number of ways things can happen over the total possible outcomes.
The number of ways we could add to 4 with two dice is 1+3, 2+2, or 3+1. That's 3 ways.
Then we count every pairing of dice in the image. That adds to 36.
So the probability of rolling to add to 4 is 3/36 or 1/12.

If the length of the 45° region of this circle is 10 inches, what is the radius of the circle? Use and round to the nearest tent

USPshnik [31]

Answer:

12.71in

step explanation:

The Length of an arc given is expressed as;

A = theta/360 * 2πr

10 = 45/360 * 2 * 3.14r

10 = 1/8 * 6.28r

Cross multiply

10 * 8 = 6.28r

80 = 6.28r

r = 80/6.28

r = 12.74in

Hence the radius is 12.71in

PLEASE HELP?

lukranit [14]

Number of ones = 60
Number of twos = 62
Number of threes = 59
Number of fours = 64
Number of fives = 63
Number of sixes = 75

Total even outcomes = total number of two, four and sixes = 62 + 64 + 75 = 201

Total outcomes = 60+62+59+64+63+75= 383

Probability if rolling an even number = 201/383

percentage= 201/383 × 100 = 52.48% ~ 52.5%
