Answer:
45 times
Explanation:
A six-sided number cube has the following numbers written on its six faces.
1, 2, 3, 4, 5, 6
As can be seen, three of the above numbers (1, 3 and 5) are odd. This means that half of the cube faces have odd numbers printed on them.
[tex]\frac{3\text{odd numbers}}{6\text{ numbers}}=\frac{1}{2}[/tex]Therefore, the probability that a toss would land on an odd number is 1/2 or 50%.
Now if we do 90 tosses, then we expect that 50% of them would give us an odd number.
Therefore, the number of tosses we expect to give an odd number is
[tex]90\times\frac{1}{2}=45[/tex]Hence, we expect the number cube to give us odd numbers 45 times out of 90 tosses.
