Answer:

0.75

Step-by-step explanation:

Given that there is a 50% chance that it will rain today and a 50% chance that it will rain tomorrow

We find that these two events are independent

A = rains today and B = rains tomorrow

A and B are independent

So we have

P(AB) =P(A)P(B)

the probability that it rains at least one of the days

= P(A or B) =P(A)+P(B)-P(AB)

=0.5+0.5-0.5(0.5)

=0.75

Answer:

3−y

2. 8

4.​​2​bh

Step-by-step explanation:

5(2x+y)=15

2 Divide both sides by 55.

2x+y=\frac{15}{5}2x+y=

​5

​

​15

​​

3 Simplify  \frac{15}{5}

​5

​

​15

​​   to  33.

2x+y=32x+y=3

4 Subtract yy from both sides.

2x=3-y2x=3−y

5 Divide both sides by 22.

x=\frac{3-y}{2}x=

​2

​

1. ​3−y

​​ 2. 8

2.Add 2y2y to both sides.

x=-8+2yx=−8+2y

2 Regroup terms.

x=2y-8x=2y−8
