A) (t+s)(x) = t(x) + s(x) = x^3 +4x^2

b) (t*s)(x) = t(x)*s(x) = (x^3)*(4x^2) = 4x^5

c) (t-s)(-1) = t(-1) - s(-1) = (-1)^3 - 4(-1)^2 = -1 -4 = -5

In a bowl of fruit there are 10 bananas, 6 apples and 4 pears.
kobusy [5.1K]

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.

P

r

o

b

a

b

i

l

i

t

y

=

number of desirable outcomes

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

1

11
