The chance of rain is 20%, the chance of it being sunny is 60%, and the chance of it
Charra [1.4K]

Answer:

0.6 = 60% probability that it is either sunny or rainy.

Step-by-step explanation:

We solve this question treating these events as Venn probabilities.

I am going to say that:

Event A: Rain

Event B: Sun

The chance of rain is 20%

This means that P(A) = 0.2

The chance of it being sunny is 60%

This means that P(B) = 0.6

The chance of it being sunny and rainy at the same time is 10%.

This means that P(A \cap B) = 0.1

Calculate, the probability that it is either sunny or rainy.

This is:

P = P(A) + P(B) - 2P(A \cap B) = 0.2 + 0.6 - 0.2 = 0.6

0.6 = 60% probability that it is either sunny or rainy.

Solve for x and y: x-3y=-8 3x+2y=31
uranmaximum [27]
<span> x = 3y - 8
</span>
Plug this in for variable  x  in equation [2]<span>
</span><span><span>  [2] 3•(3y-8) + 2y = 31 </span><span>  [2] 11y = 55 </span></span>

 Solve equation [2] for the variable  y  

<span><span>  [2] 11y = 55</span>  <span>  [2] y = 5</span> </span>

// By now we know this much :

<span><span>  x = 3y-8</span> <span>  y = 5</span></span>

<span>// Use the  y  value to solve for  x  
</span>

<span>   x = 3(5)-8 = 7 </span>Solution :<span><span> {x,y} = {7,5}</span>  Processing ends successfully</span>
