If you want to find the probability, just make a fraction of the number of times that outcome happened over the total amount of tests:

Open: 3/50= 0.06 or 6%
Closed: 7/50=0.14 or 14%
Side: 40/50= 0.8 or 80%

Hope this helps!

Multiply each set of numbers and match it with it’s product

Fynjy0 [20]

Answer:

1. $1. (\frac{5}{16}) (-2) (-4) (\frac{-4}{5})= -2 \\2. (2\dfrac{3}{5}) (\frac{7}{9})=(\frac{91}{45})\\3. (\frac{2}{3})(-4)(9)= -24\\4. (\frac{-3}{4}) (\frac{7}{8})=(\frac{-21}{32})$

Step-by-step explanation:

These are simple multiplication questions of fractions. We multiply numerator with numerators and denominators with denominators. If numerator and denominator is both divisible by same number we can divide them for simplification.

1. $(\frac{5}{16}) (-2) (-4) (\frac{-4}{5})$

$=(\frac{-10}{16}) (-4) (\frac{-4}{5})\\=(\frac{40}{16}) (\frac{-4}{5})\\=(\frac{-160}{80}) \\dividing\,\, numerator\,\, and\,\, denominator\,\, by\,\, 80\,\,\\= -2$
