Answer:
Step-by-step explanation:
Assuming that each draw is independent of the last and that each ball is equally likely to be selected makes this a binomial distribution
a.) first find the probability of selecting a black ball, 2/10 or .2
![{10\choose{4}}.2^4*.8^6=.08808384](https://tex.z-dn.net/?f=%7B10%5Cchoose%7B4%7D%7D.2%5E4%2A.8%5E6%3D.08808384)
b.) Probability of slecting a red ball: 1/10 or .1
Less than 2 is X=0 + X=1
![{10\choose0}*.2^0*.8^{10}+{10\choose1}*.2*.8^9=.3758096384](https://tex.z-dn.net/?f=%7B10%5Cchoose0%7D%2A.2%5E0%2A.8%5E%7B10%7D%2B%7B10%5Cchoose1%7D%2A.2%2A.8%5E9%3D.3758096384)
