Can you please show all work so I can understand! I have A,B,C and I just need D

Thank You

Step 2
а.
From the joint distribution, the probability of selection no crypto and no other investment is 0.64.
The probability of P (No crypton No other investments) is,
P (No crypto n No other investments) = 0. 64
Thus, the probability of P (No crypto n No other investments) is 0.64.
Step 3
b.
The probability of P (No crypto U No other investments) is,
P (No crypto U No other investments)=P (No crypto) + P (No other investments)
- P (No crypto n No other investments)
=0. 80 + 0. 72 – 0. 64
=0. 88
Thus, the probability of P (No crypto U No other investments) is 0.88.
Step 4
С.
The probability that a randomly chosen student that invests in at least 1 cryptocurrency does not have other
investments is,
P (1 – 5 crypto n No other investments)+
P (5 – 10 crypto n No other investments)+
P (2 1 crypton No other investments)
P (10 – 15 crypto n No other investments)+
P(16 + crypto n No other investments)
=0. 05 + 0. 02 + 0. 01 + 0. 00
=0. 08
