Answer:
C. They have the same chance of winning.
Step-by-step explanation:
Probability (2 tails) = 1/2 * 1/2 = 1/4
Probability( 2 heads = 1/2 * 1/2 = 1/4.
Therefore the Probability they match = 1/4 + 1/4 = 1/2.
The probability of they don't match = 1 - 1/2 = 1/2 because all probabilities add up to 1. There are only 4 possible results and their probabilities must add up to 1.
Answer:
A ≈ 12.57
Step-by-step explanation:
You have to take the formula: A = πr^2
1) Plug in what you know: A = π•2^2
2) π = 3.14 and 2^2 = 4
3) Multiply to get: 12.56637
4) Round
A ≈ 12.57
The answer is C because that's is a 90 degree angle. So you just subtract 70 from 90.
0 because 0 times anything is 0
