Line passing through the points (1, -1) and (9, 3)

Step-by-step explanation:

(3+1)/(9-1) = 4/8 = 1/2

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

y + 2/2 = 1/2x - 1/2

y = 1/2x - 3/2

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
