Question

Marissa is drawing coins from a bag that contains 5 pennies, 4 nickels, 5 m

Answer 1

a. Calculate the sum of all the coins combined = 5 + 4 + 5 + 2 =16. Then put the nickels over the sum = 4/16 = 1/4 = 0.25 = 25%

b. Add the new coins to the sum = 4/20 = 1/5 = 0.20 = 20%

c. She is more likely to draw a nickel in scenario A.

Answer 2

Answer:

Step-by-step explanation:

Total no of coins in the bag $= 5+4+5+2 =16$

a) the probability that she will draw a nickel=no of nickels/total coins

= $\frac{4}{16} =0.25$

If one penny, two dimes and one quarter added then we have total coins new as = $16+1+2+1 = 20$

the

new probability that Marissa will draw a nickel= new nickel coins/new total

= $\frac{4+0}{20} =0.20$

IN the first situation there is more likely as probability is more.
