Answer #1

P(doesn't have moderate edge condition or doesn't have a below-target bore depth) = P(doesn't have moderate edge condition) + P(doesn't have a below-target bore depth) - P(doesn't not have moderate edge condition and doesn't have below-target bore depth)

= (15 + 49 + 10 + 81)/200 + (15 + 21 + 49)/200 - (15 + 49)/200

= 155/200 + 85/200 - 65/200

= 175/200 = 0.88
