Suppose that 1010​% of a certain batch of calculators have a defective​ case, and that 1414​% have defective batteries.​ Also, 5
S_A_V [24]

Answer: Our required probability is 81%.

Step-by-step explanation:

Since we have given that

Probability of defective calculators (C)= 10%

Probability of defective batteries (B) = 14%

Probability of both defective calculators and defective batteries = 5%

So, it becomes.

P(C\cup B)=P(C)+P(B)-P(B\cap C)\\\\P(C\cup B)=10+14-5\\\\P(C\cup B)=19\%

So, probability that the calculator has a good case and good batteries is given by

100\%-19\%=81\%

Hence, our required probability is 81%.

Divide 132kg in a ratio of 3:3:5
borishaifa [10]
3 + 3 + 5 = 11 (11 total parts of the ratio.)

132 ÷ 11 = 12 (one part of the ratio)

Multiply 12 by the number of parts in the ratio:

12 × 3 = 36
12 × 3 = 36
12 × 5 = 60

Therefore, the final answer is 36:36:60 kg.
