If you draw one card from a standard deck, what is the probability that you draw a king or queen?

a)113

b)213

c)1169

d)126

The answer is B

Step-by-step explanation:

The answer is B because To find the probability we use the mutually exclusive probability formula P(A) + P(B). The probability of picking a king is [1/13]] and the probability of picking a queen is  

1 /13.

The sum is  2 /13

answer: y=0 if that is what u r looking for

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
