Answer 1

Answer:

25%

Step-by-step explanation:

Answer 2

The chance that it will rain on neither of the two days is 25%.

Given,

50% chance of rain on Saturday.

50% chance of rain on Sunday.

To Find,

It will not rain for two days.

Solution,

The event is a 50% chance of rain on Saturday.

and a 50% chance of rain on Sunday.

50% = $\frac{1}{2\\}$

It means that

Rain on Saturday or No rain on Saturday.

Rain on Sunday or No rain on Sunday.

Rain on both Saturday and Sunday.

probability of event

= $\frac{1}{2}$ ×$\frac{1}{2}$ +$\frac{1}{2}$×$\frac{1}{2}$ + $\frac{1}{2}$×$\frac{1}{2}$

= 3 × 0.25 = 0.75 0r 75%

So, the probability of an event is 1.

then,

= 1 - 0.75

= 0.25 or 25%

The chance that it will rain on neither of the two days is 25%.
