Probability=(number of favorable outcomes)/(number of total outcomes)
A=select the first gold fish.
P(A)=14/40
B=select the second gold fish
P(B)=13/39

A∩B=select two fish gold

P(A∩B)=P(A)*P(B)=(14/40)*(13/39)=182/1560=91/780

If 120% is £48, what is 100%

azamat

Answer:

Step-by-step explanation:

If we go by 20's (20% of 100) 100% is 5. Since were dealing with 120% in our case we'll be dividing by 6 to figure out what every 20% is. All we need to do it's divide 48 by 6 and we get the answer 8. So in our case every 20% is equal to 8. now to solve for 100% all we need to do is subtract 8 (20%) from 120% (48) and we find 100% is 40. We could also do 8 x 5. (remember every 1 is 20% in our case) which is also 40. Therefore, your answer is 40.
