Question

1. Suppose you take a coin and flip it 4 times in a row. After each flip you record whether the coin landed heads or tails. What is the probability you’ll get at least 2 heads?

Answer 1

Answer:

25%

Step-by-step explanation:

Great question, since a regular coin has two sides one heads and one tails. That gives us a 50% probability of it landing on either side of the coin. Since we would like to know the probability of getting 2 heads in a row, we would need to multiply the probability of the first toss landing on heads with the second toss landing on heads, like so...

$\frac{1}{2} *\frac{1}{2} =\frac{1}{4}$

So we can see that the probability of us getting two heads in a row is that of \frac{1}{4}[/tex] or 25%.
