Which pair of vectors is orthogonal? u= (-3, 2) and v = (-2, 1)
u= (1,5) and v = (-5, 1)
u = (2, 1) and v= (-4, 3)
u= (2, 3) and v = (3, 1)

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
