GaryK [48]

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)

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