a panel of 6 judges is being selected from a group of 10 males and 10 females.What is the probability of selecting exactly 3 male?

Answers

Probability of selecting exactly 3 male is equals to

What is probability?

" Probability is defined as the ration of the number of favourable outcomes to the total number of outcomes."

Formula used

Probability = $(n(S))/(n(T))$

$n(S) =$ Number of favourable outcomes

$n(T)=$ Total number of outcomes

According to the question,

Total number of males $=10$

Total number of females $=10$

Number of judges for a panel to be selected $=6$

As per given condition ,

Total number of outcomes $= 20\rm C_(6)$

Number of selecting exactly 3 males for 6 judges $= 10\rm C_3* 10\rm C_3$

Substitute the value in the formula to get the required probability,

Probability of selecting exactly 3 males $= ( 10\rm C_3* 10\rm C_3)/(20\rm C_(6))$

$= (120)/(323)$

Hence, the probability of selecting exactly 3 males is equals to $(120)/(323)$ .

Answers

Answer is choice C) Inverse property of addition; a number and its inverse are added

The number is 0.3 and its additive inverse is -0.3, which add to 0. You can flip things around to say that the number is -0.3 and its additive inverse is 0.3 to add them to the same result of 0. The order of addition doesn't matter. It's like saying 2+3 = 5 and 3+2 = 5
