It’s 60! i had that and got it correct. hope this helps :)
Answer:
46
Step-by-step explanation:
6 times 2 is 12
23 times 2 is 46
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
a. Venn diagram attached below.
b. 2 students are in neither English nor Chemistry.
c. The probability that a randomly chosen student is only taking chemistry is 24/40, or 6/10 because out of the 40 students, 24 of them take exclusively the chemistry class.
Answer:
for 20 number.
<AEB=142
<BEC=38
<DEC=142
<AED=38
Step-by-step explanation:
or, m<AEB+m<BEC=180(Straight line)
or, 6x-32+2x-20=180
or, 8x-52=180
or, x=29
replacing value of x
m<AEB=6×-32
=6*29-32
=142
m<BEC=2X-20
=2*28-20
=38
m<AED=m<BEC=38(Vertcally opposite angle)
m<DEC=m<AEB=142(Vertically opposite angle)
