Answer:
A box contains 8 green, 12 blue and 10 yellow cubes. Raphael draw at random, find the probability that it is
1.)Green cube? 8/30 = 4/15
2.)Green or Blue? 8/30 + 12/30 = 20/30 = 2/3
3.)Blue or Yellow? 12/30 + 10/30 = 22/30 = 11/15
4.)Blue? 12/30 = 2/5
A box contain 12 green, 8 red cubes, 14 blue, 6 orange and 18 yellow cubes. Gerry draw a random find the probability that it is
1.)Green cube? 12/58 = 6/29
2.)Yellow cubes? 18/58 = 9/29
3.)Yellow or Green? 18/58 + 12/58 = 30/58 = 15/29
What is the probability of randomly picking a number from 1 to 15 that is
1.) even or odd? 7/15 + 8/15 = 15/15 = 1
2.)even number or divisible by 4? 7/15 + 4/15 = 7/15
3.) odd number or divisible by 5? 8/15 × 5/15 = 8/75
btw, naka lowest term na yan ha! Galing pa yang sagot sa teacher ko nung grade 7
