You flip a coin twice. find the probability that at least one of the tosses showed heads.

The probability is 0.75[

Step-by-step explanation:

If we flip a coin twice, we have 4 possibilities, those possibilities are:

From these 4 options, 3 show heads at least one of the tosses. These 3 options are TH, HT and HH.

Taking into account that all the possibilities have the same chance, the probability is calculated as the division between 3 and 4 as:

tex]\frac{3}{4} =0.75[/tex]

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
