Of a group of 500 people, 60 are fit enough to climb mount shasta in california. the group has 300 women and 200 men. 12% of the men are fit to climb the mountain. what is the probability that a person picked at random from the group is a male or is fit to climb mount shasta?

Take 12 of 200 to determine amount of fit men

12% × 200 or .12 × 200

= 24

24 men are fit enough

so, since they are asking male + the amount of people fit enough, you must subtract the fit men from the fit people so you are not doubling the men

60 - 24 = 36

now add the fit people to the male group

so

36+200 = 236

so your answer is

236/500
118/250
59/125
47.2%
