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

USPshnik [31]

Question:

Three students were working on 630,000÷700 in math class.

a. Desiree finds the quotient is 9,000 and Micah finds the quotient is 900.

    Determine which student found the correct quotient.

b. Delilah finds her answer is 90, but she copied the expression incorrectly from the board. If her reasoning and answer for the expression she copied are correct, what expression might she have written?

Answer:

a. Micah is correct

b.

Expression = 63000 \div 700

Expression = 630000 \div 7000

Step-by-step explanation:

Given

Expression = 630000 \div 700

Desiree = 9000

Micah = 900

Solving (a): Who is correct?

To do this, we first calculate the quotient of the expression.

Expression = 630000 \div 700

Divide 630000 by 700

Quotient = 900

Hence:

Micah is correct

Solving (b): What Delilah must have copied?

We have:

Delilah = 90

There are no options to pick from. So, we just need to work out expressions that equals 0.

Possible expressions are:

Expression = 63000 \div 700

Expression = 630000 \div 7000

Suppose that Smartphone A has 256 MB RAM and 32 GB R OM, and the resolution of its camera is 8 MP; Smart- phone B has 288 MB RAM
Sonbull [250]

Answer:

A.) TRUE

B.) TRUE

C.) FALSE

D.) FALSE

E.) FALSE

Step-by-step explanation:

Given that :

SMARTPHONE A:

RAM : 256 MB

ROM : 32 GB

CAMERA RESOLUTION : 8 MP

SMARTPHONE B:

RAM : 288 MB

ROM : 64 GB

CAMERA RESOLUTION : 4 MP

SMARTPHONE C:

RAM : 128 MB

ROM : 32 GB

CAMERA RESOLUTION : 5 MP

Determine the truth value of each of these propositions.

A) Smartphone B has the most RAM of these three smart- phones.

TRUE ; 288 > (256 and 128)

B) Smartphone C has more R O M o r a higher resolution camera than Smartphone B.

C ROM > B ROM = FALSE

C CAMERA RESOLUTION > B camera resolution = TRUE

FALSE or TRUE = TRUE

C.) Smartphone B has more RAM, more R OM, and a higher resolution camera than Smartphone A.

RAM = TRUE ; ROM = TRUE ; CAMERA RESOLUTION = FALSE

TRUE and TRUE and FALSE = FALSE

d) If Smartphone B has more RAM and more R O M than Smartphone C, then it also has a higher resolution camera.

CAMERA RESOLUTION ON SMARTPHONE B IS LESS, HENCE, STATEMENT = FALSE

e) Smartphone A has more RAM than Smartphone B i f and only if Smartphone B has more RAM than Smart- phone A.

1st statement = FALSE

2nd condition = TRUE

FALSE and TRUE

= FALSE
