Share £420 in the ratio 2:5

Answer:

120:300 is in the same ratio as 2:5. Can you add the pound sign? My keyboard does not have it.

Step-by-step explanation:

Add the two parts of the ratio together

2 + 5 = 7

Find 5:7

5:7 = x:420  

5/7 = x/420              Cross multiply

7x = 5 * 420             Combine the right

7x = 2100                  Divide by 7

x = 2100/7

x = 300                      

Find the second number

420 - 300 = 120

120 : 300 is the answer

Divide top and bottom by 60

120/60 = 2

300 / 60 = 5

<h3>Answer:  Independent</h3>

For two events A and B, if the occurrence of either event in no way affects the probability of the occurrence of the other event, then the two events are considered to be <u>  independent  </u> events.

=========================================================

Explanation:

Consider the idea of flipping a coin and rolling a dice. If these actions are separate (i.e. they don't bump into each other), then one object won't affect the other. Hence, one probability won't change the other. We consider these events to be independent.

In contrast, let's say we're pulling out cards from a deck. If we don't put the first card back, then the future probabilities of other cards will change. This is considered dependent.
