The answer is 13/15.

2/5 = 12/30
2/3 = 20/30

12/30 + 20/30 - 6/30 = 32/30 - 6/30 = 26/30 = 13/15.

The sum of 31/4+42/4= 18.25

<u>Step-by-step explanation</u>:

  • The denominators are same.
  • Then add the numerators and keep the denominators same.

The sum of (31/4) + (42/4) = (31+42)/4

A bag contains 6 red balls and 3 blue balls. 4 balls are selected at random. find the probability of selecting 4 red balls.
geniusboy [140]
Assuming that the balls are not replaced; 

\frac{6}{9}* \frac{5}{8}* \frac{4}{7}* \frac{3}{6}= 5/42 

(the numbers are decreasing in the denominator as you are presumably taking out the red balls. In the denominator, there is one less ball each time since you took out a red one). 

Therefore, the probability of selected 4 red balls consecutively without replacement is 5/42. 

Hope I Helped :)
