Answer:
the probability of picking a black clothing is 12/30 (6/15), and the probability of picking a pair of pants is 17/30
Step-by-step explanation:
First we have to figure out how much will it be out of, to do that you have add the amount of clothing there is (in this case 30).
Determine how many pairs of black clothing:
you must add up the amount of black clothes so 5+7=12, so there are 12 black clothing and 30 in total so the chance is 12/30 if you want it reduced it could be 6/15.
determine how many pairs of pants:
Now it's the same as last step add up all the pairs of pants the question has so 7+10=17. so there are 17 pants out of 30 pieces of clothes so 17/30
(sorry if this isnt a good explanation, I tried)
