Answer:
85%
Step-by-step explanation:
P(a) = 25%=1/4
P(b) = 60%=3/5
P(a and b) = 1/4 + 3/5 = 5+12/20 = 17/20 = 85%
Answer:
The probability of A and B is 85%
Step-by-step explanation:
It is 85% because 25% is 0.25 or 25/100(1/4), and 60% is 0.6 or 6/10(3/5). 0.6+0.25=0.85 and to convert it back to a percentage you need to times 100%. 0.85x100%=0.85x100 with a percentage symbol =85%.
