Answer:
The probability of getting a pair of red socks is 0.322
Step-by-step explanation:
According to the given data we have that A drawer contains 11 identical red socks and 8 identical black socks, hence, the total number of socks is 19, therefore, in order to calculate the probability of getting a pair of red socks we would have to use the following formula:
probability of getting a pair of red socks=11C2/19C2
probability of getting a pair of red socks=55/171
probability of getting a pair of red socks=0.322
The probability of getting a pair of red socks is 0.322
The answer you're looking for is 83.
