The probability of getting all heads is 1 / 2^6 = 1/64 as there is only 1 event where this happens in a possible 2^6 = 64 events. It is the same as the probability of getting all tails. The probability of getting at least 1 head is 1 - p(all tails) = 63/64.
Answer:
Multiplication property of equality
Step-by-step explanation:
Given
Step 4: b = -27/8
Required
Which property justifies it?
First, it should be noted that step 4 is a result of step 3
When step 3 is multiplied by 3/8 on both sides, we have step 4;
i.e.





<em>The property that allows 3/8 be multiplied on both sides is referred to as the multiplication property of equality</em>
