Angle 3 and angle 4 are supplementary angles. Angle 3 is 88. What is the measure of angle 4?
Mademuasel [1]
Since angles 3 and 4 are supplementary, they add up to 180 degrees.

Angle 3 is 88 degrees.

To get the measure of the last angle, let's subtract 88 from 180.

180 - 88 = 92

Thus, Angle 4 has a measure of 92 degrees.

Have an awesome day! :)

Three cards are selected from a well-shuffled deck of 52 cards. Find the probability that all 3 are Aces.
SIZIF [17.4K]

Answer:

We can divide the pack of cards in two ways

Non Ace cards and Ace cards

Since there are 4 aces in a pack

No of non ace cards will be 52–4=48

The question mentions atleast 1 ace cards so i can pick 1 ace card,2 ace cards or 3 ace cards

Case1:1 Ace card

1 will pick one ace card and 2 non ace cards

It can be done in 4C1*48*C2 ways

= 4*1128 = 4 512 ways

Case 2: 2 Ace Cards

I will pick 2 ace cards and 1 non ace card

It can be done in 4C2 * 48C1 = 6 * 48 =288 ways

Case 3:3 Ace cards

It can be done in 4C3 =4 ways

Therefore the probability is

(4512+288+4)/52C3

=4804/22100=0.217
