Question

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 2323 Pennies 55 Dimes 2020 Nickels 1919 Quarters Copy Data What is the probability that you reach into the jar and randomly grab a dime and then, without replacement, a nickel

Answer 1

Answer:

The answer is "0.081"

Step-by-step explanation:

Dimes $= 55$

Calculating total coins $= (23+55+20+19) = 117$

P(for a dime) $= \frac{55}{117}$

Calculating remaining coins $= 116$

Nickels $= 20$

P(for nickel draw in second) $= \frac{20}{116}$

P(for a dime after that a nickel, without replacement)

$= \frac{55}{117} \times \frac{20}{116} \\\\= \frac{1100}{13572} \\\\=0.081$
