Mathematics
1 answer:
Paraphin [41]3 years ago
7 0

Answer:

x = 56/63

Step-by-step explanation:

\frac{5}{9}-\frac{2}{7}x  =\frac{19}{63}

\frac{19}{63} - \frac{5}{9} =\frac{-2}{7}x\\\\\frac{19-35}{63}=\frac{-2}{7}x\\\\\frac{-16}{63}= \frac{-2}{7}x\\\\\frac{-16}{63}*\frac{-7}{2} = x\\\\\frac{112}{126}=x\\\\x= \frac{56}{63}

andrey2020 [161]

Answer:

The probability that A selects the first red ball is 0.5833.

Step-by-step explanation:

Given : An urn contains 3 red and 7 black balls. Players A and B take turns (A goes first) withdrawing balls from the urn consecutively.

To find : What is the probability that A selects the first red ball?

Solution :

A wins if the first red ball is drawn 1st,3rd,5th or 7th.

A red ball drawn first, there are E(1)= ^9C_2 places in which the other 2 red balls can be placed.

A red ball drawn third, there are E(3)= ^7C_2 places in which the other 2 red balls can be placed.

A red ball drawn fifth, there are E(5)= ^5C_2 places in which the other 2 red balls can be placed.

A red ball drawn seventh, there are E(7)= ^3C_2 places in which the other 2 red balls can be placed.

The total number of total event is S= ^{10}C_3

The probability that A selects the first red ball is

P(A \text{wins})=\frac{(^9C_2)+(^7C_2)+(^5C_2)+(^3C_2)}{^{10}C_3}

P(A \text{wins})=\frac{36+21+10+3}{120}

P(A \text{wins})=\frac{70}{120}

P(A \text{wins})=0.5833
