Answer:
3/8.
Step-by-step explanation:
The probability of a head or a tail on one toss of a single coin is 1/2.
So the required probability when 3 coins are tossed of getting say 3 heads = (1/2)*3 = 1/8.
The probabilities are multiplied because each event ( 1 coin tossed) is independent of the others.
There are 3 ways to get 2 H and 1 tail (HHT, HTH and THH) so the answer is 3 * 1/8
= 3/8.

Step-by-step explanation:
The wrestler's weight before he went on his diet is 78 kg
<h3>How to find the y-intercept?</h3>
The formula for slope is;
m = (y2 - y1)/(x2 - x1)
Thus, using two points we have;
m = (93.6 - 85.8)/(3 - 1.5)
m = 5.2
At the start of his diet, time in months = 0 months and so x = 0. Thus;
5.2 = (85.8 - y0)/(1.5 - 0)
5.2 * 1.5 = 85.8 - y0
y0 = 85.8 - (5.2 * 1.5)
y0 = 85.8 - 7.8
y0 = 78 kg
Thus, the wrestler's weight before he went on his diet is 78 kg
