4,3 and 1,0 that’s the answer
There are 8 possible outcomes when you throw a coin three times:
Out of these combination, the ones with exactly two heads are
So, 3 combinations out of 8 have exactly two heads. This means that the probability of having two heads with three coin throws is 3/8
First work out (5/2)³ by cubing both the numerator and denominator to give: 125/8
then work out (3/4)² by squaring both the numerator and denominator to give: 9/16
then divide 125/8 by 9/16
using the stay-change-flip method of division:
the first term stays the same, the divide becomes multiply and the second fraction is flipped upside down.
so:
125/8 x 16/9 =2000/72
then just divide 2000 by 72 to give: 27.78 to 2 d.p
therefore the greatest whole number than 27.78 is 27.
The answer is D) 12
