Answer:
2/91.
Step-by-step explanation:
There are 15 marbles in the bag.
Prob(First draw is red) = 5/15 = 1/3.
Prob(Second draw is red) = 4/14 = 2/7.
Prob(Third draw is red) = 3/13.
So probability that all 3 are red = .1/3 * 2/7 * 3/13
= 6/273
= 2/91.
Answer:
percent decrease is 30%
Step-by-step explanation:
Step one:
given data
Cost of scooter= $15.50
selling price= $10.75
Step two:
%decrease = Cost price-selling price/cost price
%decrease = (15.5-10.75/15.5)*100
%decrease =( 4.75/15.75)*100
%decrease = 0.30*100
%decrease =30%
therefore the percent decrease is 30%
