In a box there are six envelopes each containing two cards. Three of the envelopes contain two red cards, two of them contain a

Sphinxa [80]

Answer:

$\frac{2}{5}$

Step-by-step explanation:

3 envelopes having 2 red card

2 envelopes having 1 red card and 1 black card

1 envelope having 2 black cards

We are given that . An envelope is selected at random and a card is withdrawn and found to be red.

So, No. of ways of envelope having red card = 3+2 = 5

No. of required ways of envelope having 1 red card and 1 black card = 2

So, probability of getting an envelope having 1 red card and 1 black card = $\frac{2}{5}$

Hence The chance the other card is black is $\frac{2}{5}$

ANSWER ASAP PLEASE !!!AND CORRECT!!<br> OTHER ANSWER CHOICE IS 19 feet, 6 inches.

DiKsa [7]

well you know that the yellow rope is 18' shorter then the white rope X 2,

so you would take 101/2 feet and add 18 inches, then you would need to divide that by two to get how long the white one is.

10 1/2 feet + 18 inches = 12 feet

12 feet divided by 2 is 6 feet
