Answer 1

4)
P( price 1 OR 4 | day 1 OR 3)
P( price 1 OR 4 | day 1) + P( price 1 OR 4 | day 3)
=(66+53)/263+(69+74)/280
0.9632

5)
P(day 1&2&3 OR price 1&2)
P(day 1&2&3 with price 1) + P(day 1&2&3 with price2 )
=(178+219)/800
0.49625

6)
P(PRICE 2 or 3)
=(219+209)/800
0.535

7)
P(price>=1 AND day1&2&3)
=(178+219+209+194)/800
