Describe the relationship between the two sets a and b if a ⊆ b. (no picture is provided in the question)

Set A is a subset of set B. It means that every element of set A should be present in set B.

Step-by-step explanation:

A ⊆ B

Set A is a subset of set B. It means that every element of set A should be present in set B.

i.e for all a ∈ A then a ∈ B

Example:

Let set A = {1,2,3}

and B = { 1,2,3,4,5,6}

then A ⊆ B because every element in set A {1,2,3} is also present in set B {1,2,3,4,5,6}

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
