Number of outcomes when flipping a coin = 2
Favorable outcome is landing on head.
So,number of favorable outcomes = 1
Probability of getting a head when flipping a coin = [tex] \frac{1}{2} [/tex]
Number of outcomes when rolling a dice = 6
Favorable outcomes are rolling 4,5 or 6.
So,number of favorable outcomes = 3
Probability of getting 4 or a bigger number when rolling a dice = [tex] \frac{3}{6}= \frac{1}{2} [/tex]
Thus the probability of getting a head when flipping a coin and getting a number equal to or greater than 4 when a dice is rolled = [tex] \frac{1}{2}* \frac{1}{2} = \frac{1}{4} [/tex]
So, option A gives the correct answer
