You randomly select a card from a 52-card deck. find the probability of selecting an ace or a jack

There are 4 aces and 4 jacks. So there are 4+4 = 8 cards that we want. This is out of 52 cards total.

Divide and reduce: 8/52 = 2/13

The answer as a fraction is 2/13

In decimal form, the answer is approximately 0.1538 which converts to 15.38%

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
