Answer:

It is 2/121.

Step-by-step explanation:

For the first draw, the probability of picking P is 1/11 since there is only one P letter in the 11 letters. If we replace the P after drawing, then for the second draw, the probability of drawing I is 2/11 since there are 2 I's in the 11 letters.

Since the events are seperate, the probability of picking P and then picking I is (1/11)x(2/11) = 2/121.

I hope this answer helps.

Write the point-slope form of the given line that passes through the points (-4, -1) and (3, -3). Identify (x1, y1) as (-4, -1).
kotegsom [21]

Answer:

y + 1 = -2/7 (x + 4)

Step-by-step explanation:

Find the slope using y₂ -y₁ /x₂ -x₁

m = -3 + 1 / 3 + 4

m = -2/7

Plug the m, x and y into the point slope equation y - y₁ = m ( x - x₁)

y + 1 = -2/7 (x + 4)
