<span>it all looks confusing when we try to juggle with all those numbers in the head. The problem can be solved systematically by constructing a contingency table.
</span>role/gender B G total
speaking...... 4 4 8
<span> silent............ 4 8 12
total............. 8 12 20
</span>Probability of a child having a speaking part is therefore
(4+4)/20=8/20=2/5
a. 2/5
I am assuming you mean mL. So milliliters.
Milli is the thousandths.
1,000 milliliters is 1 liter.
That would mean that 10L is greater than 1,00mL.
Hope this helps!
2 1/4+1 1/4=3 1/2
or 3.5 (3 and a half yards. )
