Answer:
0.915
Step-by-step explanation:
rolling a 5 is a 1/6 probability
tossing tails is a 1/2 probability
doing both is a 1/6 * 1/2 = 1/12 probability
A:B:C = 2:4:4
A = 210km
So B & C = 210*2 = 420km
Total distance = 210 + 420 + 420
= 1050km
9 out of 20. 9/20. Because since there are 9 red caps and the total are 20, that means that out of the 20, only 9 of them are red.
