Idk but I think the answer you are looking for is D
22.
Alternate angles23.
4: (

, substitute b with 10 and a with 20 and you get 4.)

0.28: 0.12 + 0.60 = 0.72. Probability is always out of 1, so 1 - 0.72 should give you the probability of losing, which is 0.28.
6.4$
Solution:
Divide 40 and 100(there must always be 100 when solving percentage) then it would be equal to 0.4
after it Multiply it to 16
so we get 6.4.
