So we know that the dice had 6 numbers which is 1 to 6, and we know that the odd number between 1 and 6 is 1,3,5. As a result, the probability of rolling an odd number on a fair die is 3/6 or 1/2, and we already know that probability of flipping a tail on a coin is 1/2, so I just take 1/2 times 1/2 to get 1/4 which is C. Hope it help!
A 2500 you want the biggest sample size possible for more accurate results
1/2 = 4/8
3/8 = 3/8
8 is the common denominator between these two fractions
B. if two lines are perpendicular, then they intersect to form four right angles.
