If a coin is tossed 5 times, and then a standard six-sided die is rolled 4 times, and finally a group of three cards are drawn f
Step2247 [10]

Answer:  5,499,187,200

<u>Step-by-step explanation:</u>

A coin is tossed 5 times.  

There are two options (heads or tails) so the possible outcomes are: 2⁵

A six-sided die is rolled 4 times.

There are six options so the possible outcomes are: 6⁴

A group of 3 cards are drawn (without replacement).

The first outcome has 52 options, the second has 51 options, and the third has 50 options: 52 x 51 x 50

Now if we want the coin AND the die AND the cards, we have to multiply all of their possible outcomes:

     2⁵ x   6⁴  x  52 x 51 x 50

=   32 x 1296 x 132,600

=  5,499,187,200

Simplify the expression to one number using order of operations:
geniusboy [140]
<h2><u>COMBINED OPERATIONS</u></h2><h3>Exercise</h3>

First, let's solve the subtraction (in parentheses):

\mathsf{\dfrac{-8\left(2-6\right)}{2}}

\mathsf{\dfrac{-8(-4)}{2}}

Now, let's solve the multiplication. Remember: in multiplication, two negative numbers will give a positive number:

\mathsf{\dfrac{-8(-4)}{2}}

\mathsf{\dfrac{32}{2}}

Finally, let's solve the division:

\mathsf{\dfrac{32}{2} = 16}

<h3><u>Answer</u>: 16</h3>
