Answer:

0.71 to 2 decimal places.

Step-by-step explanation:

The Probability that a letter A through G is drawn in 1 draw = 7/26.

The probability that a different draw other A-G is made = 1 - 7/26 = 19/26.

Probability ( No A-G drawn in 4 draws) = (19/26)^4 = 0.2852.

Therefore, the probability that A-G is drawn at least once = 1 - 0.2852.

= 0.71 to 2 decimal places.

Use the distributive property to express 15+45

Nuetrik [128]

Answer:
15(1+3)

Explanation:
The distributive property can be generally expressed as follows:
ab + ac = a(b+c)

The given expression is:
15 + 45

We know that:
15 = 1*15
45 = 3*15

Therefore, the given expression can be written as:
1*15 + 3*15

Taking 15 as a common factor and applying the above rule, we will reach the following expression:
15(1+3)

Hope this helps :)
