question:

steven puts some discs into a bag. He will pull out one disc from the bag that will decide if he goes to bed , cooks a meal , has a drink , or watches TV.

the probability of each occurring is:

bed= 1/4
meal= ?
drink= 1/6
t.v= 1/3

a) what was the probabiliy of steven cooking a meal?

b) which event is most likely to happen

c) if 4 discs had the ,drink symbol , how many discs had the bed symbol on them?

thank you!

a) it says he will pull out one disk so that means that the sum of the probability of the events must equal 1

b) the event that has the highest probability

c) Look at the question like this: if 4 discs provide a probability of 1/6 for the event to happen, how many disks will provide a probability of 1/4 for the event to happen. Hint: if there are 24 disks, 4/24 = 1/6 chance of having a drink. x/24 = 1/4 chance of going to bed.
