A card is chosen at random from a standard deck of 52 playing cards what is the probability that the car chosen is a queen

1/13

Step-by-step explanation:

Note 1: In a deck of 52 playing cards, there are four queen cards.

Probability =desired outcome/total outcome

desired outcome in this case is 4, as a deck of card contains the standard 52 cards, which contains 4 queen cards.

While Total outcome is the total number of cards- 52

Pr (queen cards) = 4/52, simplified to the lowest fraction will give 1/13.

I hope this is clear, please mark as brainliest answer.

40 is the final : )

x = central angle apc = measure of minor arc ac

the two angles x and 30 add to 180, so x+30 = 180 and x = 180-30 = 150. the measure of minor arc ac is 150 degrees.

what we need to do from here is find the circumference and then multiply it by x/360 since there are 360 degrees in a circle. in this case, x = 150, so x/360 = 150/360 = 15/36 = 5/12. the shortest distance along the curve from a to c is 5/12 of the distance around the entire circle (aka circumference)

c = circumference

c = pi*d

c = pi*24

c = 24pi

now multiply this by 5/12 to get

distance along minor arc ac = (5/12)*(circumference)

distance along minor arc ac = (5/12)*(24pi)

distance along minor arc ac = 10pi

the formula you can use is

l = (x/360)*pi*d

with

l = length of minor arc

x = central angle

d = diameter

which essentially is the steps we took though a bit differently.
