Question

In a bowl of fruit there are 10 bananas, 6 apples and 4 pears.

Answer 1

Answer:

P(0,0) = 2/12 times 1/11 = 1/66

Step-by-step explanation:

For probability questions, think of each event happening separately, it makes the maths easier to understand. For example, in this question, do not think of the two boys taking a fruit at the same time - that makes the maths complicated

.

Let Daniel take a fruit first, then Sean can take a fruit. There are two parts to consider.

total number of possible outcomes

For Daniel: there are 12 different pieces of fruit in the bowl, he just takes one without choosing a specific fruit. (random)

The chance that Daniel takes an orange is

2

12

Of the 12 pieces of fruit. 2 are oranges.

Now Sean: the numbers of fruit in the bowl have changed. There are now only 11 pieces of fruit in the bowl, and only 1 is an orange.

The chance that Sean takes an orange is
