If a fair coin is tossed 6 times, what is the probability, to the nearest thousandth, of getting exactly 6 tails?
xxTIMURxx [149]
<h2>Answer:</h2>

\frac{1}{64}

<h2>Step-by-step explanation:</h2>

The\ probability\ of\ tails\ per\ flip\ is\ \frac{1}{2}

so\ the\ probability\ of\ getting\ six

tails\ is

\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}=\frac{1}{64}

The\ probability\ of\ getting\ tails\ every

time\ you\ multiply\ them\ is\ the

probobility\ of\ getting\ tails\ all\ six

times?

<em>I hope this helps you</em>

Mr. Fat needs 20 minutes to eat a pound of cereal, while Mr. Thin needs 30 minutes. If they eat together, how long does it take
marishachu [46]
36 minutes.

(1/20)x+(1/30)x=1solve for x (x=0.8333333333......)
Considering they take the same times for all 3 pounds,
That would mean that since 1 pound takes 12 minutes, then 3 pounds take 36 minutes
