Question

Joanna has nickels, dimes, and pennies in a jar. The probability of drawing a nickel from the jar is 0.3, the probability of drawing a dime is 0.2, and the probability of drawing a penny is 0.5. Joanna picks a coin from the jar 240 times, replacing each coin before the next draw. About how many times would Joanna pick a dime in 240 draws?
A.
36
B.
48
C.
100
D.
120

Answer 1

Answer:

Option(B) 48 is correct

Step-by-step explanation:

Here P(dime)=0.2

Total events =240

P(dime) = Favoring events /240

Favoring events=240*P(dimes)

=240*0.2=48

Option(B) 48 is correct
