The first thing you need to do is add up the right hand column. You should get a total of 200 for the numbers 1 to 6.

So the probability for 1
30 / 200 = 0.15

Probability for 2
44/200 = 0.22

Probability for 3
12/200 = 0.06

Probability for 4
28/200 = 0.14

Probability for 5
54/200 = 0.27

Probability for 6
32/200 = 0.16

Check.
You should check these probabilities. They should add up to 1
0.15
0.22
0.06
0.14
0.27
0.16
====
1.00 which checks so you can depend on the answers being correct.

Taji has a total of 98 quarters and dimes. their value is $18.20 how many quarters does taji have?
scZoUnD [109]

Answer:

Taji has a total of 56 quarters.

Step-by-step explanation:

Let <em>x</em> be the number of quarters that Taji has.

Amount in terms of quarter =0.25 \times x

Let <em>y</em> be the number of dimes that Taji has.

Amount in terms of quarter =0.10 \times y

As per question statement:

x + y = 98 ...... (1)

Total amount is $18.20 as given in the question statement.

\Rightarrow 18.20 = 0.25 \times x + 0.10 \times y\\\Rightarrow 25x + 10y = 1820 ...... (2)

Solving equations (1) and (2):

Multiplying equation (1) by 10 and subtracting from equation (2):

25x + 10y -10x -10y= 1820 - 980\\\Rightarrow 15x = 840\\\Rightarrow x = 56

<em>x </em>is the number of quarters that Taji has.

So, Taji has a total of 56 quarters.
