SOLUTION:
= 114 - ( - 29 )
= 114 + 29
= 143
Hope this helps! <3
2% as a reduced fraction is 2/100 = 1/50
As likely as not. There are 26 red cards and 26 black cards, so there is a 50% chance of getting red and a 50% chance of getting black.
Since 0.94 is the probability of both devices detecting, the probability of neither doing so is 1-0.94=0.06, answer 3.
Answer:
(5/7 - 1) * (2/3 + (1/6 - 1/9) * 18/5 + 1/15) - (2/7 + 1/3) * (-7/13)
= (5/7 - 7/7) * (2/3 + (3/18 - 2/18) * 18/5 + 1/15) - (6/21 + 7/21) * (-7/13)
= (-2/7) * (2/3 + 1/18 * 18/5 + 1/15) - 13/21 * (-7/13)
= (-2/7) * (2/3 + 1/5 + 1/15) + 7/21
= (-2/7) * (10/15 + 3/15 + 1/15) + 1/3
= (-2/7) * 14/15 + 1/3
= -4/15 + 1/3
= -4/15 + 5/15
= 1/15
