Answer: 10 over 40 plus 9 over 39
Step-by-step explanation:
Since, the total number of white box = 10,
Red box = 10,
Green box = 10,
And, Blue box = 10,
Thus, the total number of boxes = 10 + 10 + 10 + 10 = 40
The probability of receiving white box by first winner = White box / Total box
= [tex]\frac{10}{40}[/tex]
Since, the replacing is not allowed ( Because, here boxes are allotted )
Thus, the remaining white box = 10 - 1 = 9,
And, the remaining total boxes = 40 - 1 = 39,
Thus, the probability of receiving white box by second winner = Remaining white box / Remaining total box
= [tex]\frac{9}{39}[/tex]
Hence, the probability of the first winner receiving a white box and the second winner also receiving a box of the same color
= [tex]\frac{10}{40}\times \frac{9}{39}[/tex]
Which is required expression.
