Question

What is the probability of tossing a penny and landing on heads three times in a row

Answer 1

Answer:

$\boxed {\frac{1}{8}}$

Keys:

• $\frac{a^x}{b^x} = \frac{?}{?}$

For this problem, the exponents will be 3 since the coin is being tossed 3 times, meaning we multiply the number next to the exponent by itself the number of times the exponent says to. On the other hand, we have two sides of a coin; heads and tails, so we represent heads with the fraction of one-half.

Step-by-step explanation:

$\frac{1^3}{2^3} = \frac{1}{8}$

Answer 2

$|\Omega|=2^3=8\\|A|=1\\\\P(A)=\dfrac{1}{8}=12.5\%$
