A person draws a card from a hat. Each card is one color, with the following probabilities of being drawn: 1/25 for yellow, 1/10 for green, 1/20 for purple, and 1/15 for white. What is the probability of pulling a green or white card, written as a reduced fraction?

i think c. but don't trust it.

step-by-step explanation:

1/4 because there is 4 grades.

answer: b

step-by-step explanation: im sorry bro bro but thats not a eqation the human mind can answer and plus im a devil

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
