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
Answer:
78.0 kilo
Step-by-step explanation:
85.8- 93.6= 7.8
101.4-93.6= 7.8
85.8-7.8 = 78.0 kilo
Tan x=opposite/adjacent
cot x=adjacent/opposite
so you need to inverse the fraction
tan x=.78 as a fraction is 78/100
-> inversed= 100/78=1.28=cot x
so it is the second option
15 is the answer because 8-5 is 3 and 3 and 4 is 12 so 12 plus 3 is 15
