Hello!

You first find out how many objects there are in total

4 + 9 + 3 = 16

Then you find the probability of Liliana picking a orange

Since there are 4 oranges and 16 things to pick she has a 4/16 chance of getting an orange

Next you find the probability of Liliana picking a pear

There are 3 pears and 16 items to pick so she has a 3/16 chance

Then you add them together to find the chance of either happening

4/16 + 3/16 = 7/16

So she has a 7 out of 16 chance of getting an orange or a pear

The answer is 7/16

Hope this helps!

A scientist wants to research the potential spread of germs by contact. she knows that the number of possible handshakes within

Viefleur [7K]

Given that the number of possible handshakes within a group of n people is given by the equation:

 $N= \frac{1}{2} (n^2-n)$

Given that there are 105 people at a party, the number of possible handshakes is given by:

 $N= \frac{1}{2} (105^2-105) \\ \\ = \frac{1}{2} (11025-105)=10920$
