In tossing four fair dice, what is the probability of tossing, at most, one 3
11Alexandr11 [23.1K]

<u>Answer- </u>

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

<u>Solution-</u>

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

Fred and Sue want to fence in a rectangular area in their yard for a vegetable garden. Suppose that they have 30 feet of fencing
larisa [96]

Answer:

a=35x−x^2

Step-by-step explanation:

Having  

70 ft of fencing with a  

width of x

feet and knowing the perimeter of a rectangle is  

p=2w+2l

we can state the length of the garden as:

70=2x+2l

and solving for  l

we know the length with be:

2l=70−2x or l=35−x  

And then knowing the formula for the area of a rectangle is  

a=w⋅l

we can write the equation as:

a=x⋅(35−x)a=35x−x^2
