if each option is equally likely within each category what is the probability that he wore a black shirt and his tennis shoes?

group of answer choices

1/5

1/10

1/2

7/10

7/10

Step-by-step explanation:

The probability that he wore a Black shirt is 1/5

the probability that he wore his tennis shoes is 1/2 :

1/5 + 1/2 = 7/10

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
