There are 13 yellow cards, 6 blue, 10 red, and 8 green cards in a stack of cards faced down. Once a card is selected, it is not replaced. Find the probability of 2 blue cards

0.08

Step-by-step explanation:

Given data

Sample space

13 yellow cards

6 blue

10 red

8 green cards

Sample size= 13+6+10+8

=37

probability of 2 blue cards

= 6/37+5/36

=42+42/962

=84/962

=0.08

Hence the  probability  is 0.08

answer: 75°

step-by-step explanation:

∠esk is the supplement of ∠edk, so is 100°. ∠esd = 1/2·arc ed, so is 25°.

since ∠esk = ∠esd + ∠dsk

you have 100° = 25° + ∠dsk . .

fill in known values 75° = ∠dsk . . . . .

subtract 25°
