Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 18 Pennies 13 Dimes 18 Nickels 13 Quarters What is the probability that you reach into the jar and randomly grab a nickel and then, without replacement, another nickel? Express your answer as a fraction or a decimal number rounded to four decimal places.

0.0809

Step-by-step explanation:

The jar contains 18 Pennies, 13 Dimes, 18 Nickels and 13 Quarters

Total number of coins = 18+13+18+13 = 62 coins

The probability that you reach into the jar and randomly grab a nickel and then, without replacement, another nickel?

At first, there are 18 nickels contained in the 62 total coins

After picking a nickel, there are 17 nickels contained in 61 total coins now.

This probability = (18/62) × (17/61) = 0.0809

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
