A waether forecast predicts a 30% chance of rain for each of the next 3 days. Describe a way to stimulate the chance that it wil

DerKrebs [107]

Using a binomial distribution considering there's a 30% chance it will rain on any of the three days:

The probability of it raining on 0 days is (1)(0.7)(0.7)(0.7) = 34.3%. 
The probability of it raining on 1 day is (3)(0.3)(0.7)(0.7) = 44.1%. 
The probability of it raining on 2 days is (3)(0.3)(0.3)(0.7) = 18.9%. 
The probability of it raining on 3 days is (1)(0.3)(0.3)(0.3) = 2.7%. 

There's a 65.7% chance that it will rain at least once over the three-day period.

I need to know the answer to the question with the circle

KATRIN_1 [288]

___________________________

◆ AREA RELATED TO CIRCLES ◆ ___________________________

As shown in the figure ,

Radius of circle = 5 cm

Side of square = 2 × (Radius of inscribed circle)

Side of square = 2 × 5 cm

Side of square = 10 cm = a

___________________________

Now ,
Area of shaded region = (Area of square) - ( Area of inscribed circle )

Area of shaded region =
${a}^{2} - \pi {r}^{2}$

Area of shaded region =
${10}^{2} - \frac{22}{7} \times {5}^{2}$

Area of shaded region = 100 - 78.571

$= 21.428 \: ans.$

The total number of marbles in the jar can be found by adding all the numbers of marbles given:

15+5+10 = 30

Out of 30 total marbles, 15 are red marbles. We can write the ratio as:

15:30

This ration can be simplified to:
