Mario has large drawer with only white and blacks socks. He has 3 times as many blacks socks as white socks. If Mario randomly selects 10 socks what other info is necessary to do.dthe probability that he wi get at least 3 pairs of blacks socks.

F. Total number of sock pairs in the drawer
G. Ratio of white socks to black socks
H. Total number of times he selects a pair
J. Number of red socks in tbe drawer

To calculate the probability that Mario will get at least 3 pairs of black socks when randomly selecting 10 socks, we need to know the total number of sock pairs in the drawer (F). This is because we need to find the probability of getting 3 or more pairs of black socks out of all the possible combinations of 10 socks.

Since we know that Mario has 3 times as many black socks as white socks, we also need the ratio of white socks to black socks (G) to determine the number of white and black socks in the drawer.

The total number of times Mario selects a pair of socks (H) is not directly relevant to the calculation of the probability since it only specifies the number of selections, not the specific colors of the socks.

The number of red socks in the drawer (J) is not relevant either as it is not mentioned in the question or used in the calculation.

So, in order to calculate the probability, we only need the total number of sock pairs (F) and the ratio of white socks to black socks (G).
