Gre4nikov [31]

Answer:

i. $P(A) = \frac{1}{10}$

ii. $P(B) = \frac{1}{10}$

iii. $P(A) = \frac{3}{5}$

iv. $P(B) = \frac{2}{5}$

Step-by-step explanation:

Given

Time: 07 2(A) 5(B)

Calculating (a)

First, we need to list out the possible sample space, S of A

$S = \{0,1,2,3,....,9\}$

$n(S) = 10$

Probability of A being a 4 is the number of occurrence of 4 divided by the number of sample space

$A = \{4\}$

$n(A) = 1$

Hence;

$P(A) = \frac{n(A)}{n(S)}$

$P(A) = \frac{1}{10}$

Calculating (b)

First, we need to list out the possible sample space, S of B

$S = \{0,1,2,3,....,9\}$

$n(S) = 10$

Probability of B being a 8 is the number of occurrence of 8 divided by the number of sample space

$B = \{8\}$

$n(B) = 1$

Hence;

$P(B) = \frac{n(B)}{n(S)}$

$P(B) = \frac{1}{10}$

Calculating (c)

Using the sample space in (a)

$n(S) = 10$

Probability of A being less than 6 is the number of occurrence of less than 6 divided by the number of sample space

$A = \{0,1,2,3,4,5\}$

$n(A) = 6$

Hence;

$P(A) = \frac{n(A)}{n(S)}$

$P(A) = \frac{6}{10}$

$P(A) = \frac{3}{5}$

Calculating (d)

Using the sample space in (b)

$n(S) = 10$

Probability of B being greater than 5 is the number of occurrence of greater than 5 divided by the number of sample space

$B = \{6,7,8,9\}$

$n(B) = 4$

Hence;

$P(B) = \frac{n(B)}{n(S)}$

$P(B) = \frac{4}{10}$

$P(B) = \frac{2}{5}$

How can you write 72+(8+19) to make it easier to add

max2010maxim [7]

There's a key problem in this question compelling you to actually rewrite it like that! Mathematically that is inaccurate and incorrect. If you do 72(8+19) it seems as if you are going to do 8+19*72 as in algebra whatever is outside the bracket is bound to go multiplied so technically (8+19)+72 would make more sense and the answer is

Using bidmas do the brackets first

8+19= 27
27+72=99
