In tossing four fair dice, what is the probability of tossing, at most, one 3

11Alexandr11 [23.1K]

Answer-

In tossing four fair dice, the probability of getting at most one 3 is 0.86.

Solution-

The probability of getting at most one 3 is, either getting zero 3 or only one 3.

$P(A) =The \ probability \ of \ getting \ zero \ 3 =(\frac{5}{6})(\frac{5}{6})(\frac{5}{6})(\frac{5}{6})=\frac{625}{1296} =0.48$ ( ∵ xxxx )

$P(B) = The \ probability \ of \ getting \ only \ one \ 3 =(4)(\frac{1}{6})(\frac{5}{6})(\frac{5}{6})(\frac{5}{6}) = 0.38$ ( ∵ 3xxx, x3xx, xx3x, xxx3 )

P(Atmost one 3) = P(A) + P(B) = 0.48 + 0.38 = 0.86

When jeremy gets his allowance he agrees to save part of it his savings and expenses are in the ratio of 7:5 if his daily allowa

nignag [31]

He saves $ 1.75 each day from his allowance.

Explanation

The ratio of his savings and expenses is 7 : 5

Lets assume, his savings = 7x dollar and his expenses is 5x dollar

Given that, his daily allowance is $3. So....

$7x+5x=3\\ \\ 12x=3\\ \\ x=\frac{3}{12}= \frac{1}{4}= 0.25$

So, the amount of his savings each day $=7x= (7*0.25)dollar= 1.75 dollar$

Choose all equivalent expression(s).

ElenaW [278]

Given:

The given expression is $a b^{-3 x}$

We need to determine the equivalent expression.

Equivalent expression:

Let us determine the equivalent expression.

The equivalent expression can be determined by simplifying the given expression.

Hence, let us apply the exponent rule to simplify the given expression.

Thus, applying the exponent rule, $a^{-b}=\frac{1}{a^{b}}$ , we get;

$a(\frac{1}{b^{3x}})$

Rewriting the expression, we get;

$a(\frac{1^{3x}}{b^{3x}})$

Simplifying, we get;

$a\left(\frac{1}{b}\right)^{3 x}$

Thus, the equivalent expression is $a\left(\frac{1}{b}\right)^{3 x}$

Hence, Option C is the correct answer.
