Verified Answer :

Probability of getting a Head = 1/2

The number could be 3, 4, 5, or 6

Total = 4 out of the total of 6

Probability = 4 / 6 =2/3

Head and greater or equal to 3 =    1/2  *   2/3 =   1/3

D.

Answer:

D)  \(\frac{1}{3}\) .

Step-by-step explanation:

Given : getting heads when flipping a coin and getting a number greater than or equal to 3 when rolling a single die.

To find : What is the probability of head and number greater than or equal to 3.

Solution : We have given that Flipping a coin :

Probability of getting head = \(\frac{1}{2}\).

Total number of die = 1,2,3,4,5,6

Getting number 3 or greater than 3 = 3 ,4,5,6

Probability of getting 3 or greater than 3 =  \(\frac{4}{6}\).

                                                                   =  \(\frac{2}{3}\).

Probability ( A and B) = P(A) P(B).

Probability ( head and number greater than or equal to 3) =  \(\frac{1}{2}\)  \(\frac{2}{3}\).

Probability ( head and number greater than or equal to 3) =  \(\frac{2}{6}\) .

Probability ( head and number greater than or equal to 3) =   \(\frac{1}{3}\) .

Therefore, D)  \(\frac{1}{3}\) .
