Math Problem Statement

You flip a coin two times and roll a six sided die find the probability of getting two heads and rolling a 2

Solution

To solve this probability problem, let's break it down step by step:

  1. Coin flips:

    • When you flip a fair coin, the probability of getting heads on any single flip is 12\frac{1}{2}.
    • Since the coin is flipped twice, and we want two heads, the probability of this is: P(two heads)=12×12=14.P(\text{two heads}) = \frac{1}{2} \times \frac{1}{2} = \frac{1}{4}.
  2. Die roll:

    • A standard six-sided die has six faces (1 through 6). The probability of rolling a 2 is: P(rolling a 2)=16.P(\text{rolling a 2}) = \frac{1}{6}.
  3. Combined probability:

    • Since the events are independent (the coin flips don't affect the die roll), we multiply the individual probabilities: P(two heads and rolling a 2)=14×16=124.P(\text{two heads and rolling a 2}) = \frac{1}{4} \times \frac{1}{6} = \frac{1}{24}.

Thus, the probability of getting two heads and rolling a 2 is 124\frac{1}{24}.

Tip: When events are independent, multiply the probabilities of each event to find the overall probability.
