The probability will include:
P(A and 1) = 1/24
P(C and 2) = 1/12.
P(B and 3) = 1/12.
P(A and 4) = 1/12
<h3>How to calculate the probability?</h3>
The probability of P(A and 1) will be:
= 1/4 × 1/6
= 1/24
The probability of P(C and 2) will be:
= 1/4 × 2/6
= 1/12
The probability of P(B and 3) will be:
= 2/4 × 1/6
= 1/12
The probability of P(A and 4) will be:
= 1/4 × 2/6
= 1/12

Answer:
<h2>
A. 1 and 1
</h2><h2>
D. 6 and 1/6
</h2><h2>
E -4/7 and -7/4</h2>
Step-by-step explanation:
The question is incomplete. Here is the complete question.
Which pairs of numbers represent a number and its reciprocal?
A. 1 and 1
B. 2/3 and -3/2
C. 1/2 and 5
D. 6 and 1/6
E -4/7 and -7/4
Reciprocal of a number is simply 1 divided by such number. For example the reciprocal of a is 1/a where is any number.
Based on the definition, the following pair of numbers represent a number and its reciprocal
1 and 1
The reciprocal of 1 is 1/1 which is equal to 1
6 and 1/6;
Since I can divide 1 by 6 to get 1/6 , this means that 1/6 is the reciprocal of 6. The pair 6 and 1/6 therefore represent a number and its reciprocal.
-4/7 and -7/4
reciprocal of -4/7 will be 1/(-4/7) = 1 * 7/-4 = -7/4. This shows that -7/4 is the reciprocal of -4/7 hence -4/7 and -7/4 represents a number and its reciprocal.
