Answer:

0.05

Step-by-step explanation:

To find P(event b) you would do 1- P(not event B) which in this problem would be seen as 1-(0.95)= 0.05

<h3>Answer is   0.05</h3>

The two events of B happening, or B not happening, are complementary events. One or the other must happen. There is no overlap so both events cannot happen simultaneously. This means the two probabilities add to 1, which represents 100%

P(event B) + P(not event B) = 1

P(event B) = 1 - P(not event B)

P(event B) = 1 - 0.95

P(event B) = 0.05

Airida [17]

Answer:

e) 294 children

Step-by-step explanation:

Since there are 394 children in total and 169 do not like either ice-cream, the number of children who likes at least 1 ice cream is

394 - 169 = 225 children

Out of 225 children, 150 like pistachio icecream, some of them may like both. Therefore the number of children who likes ONLY chocolate icecream is

225 - 150 = 75 children

Similarly, out of 225 children, 175 like chocolate icecream, some of them may like both. Therefore the number of children who likes ONLY pitaschio icecream is

225 - 175 = 50 children

So the total number of children who like at most only 1 kind of ice cream is

75 + 50 + 169 = 294 children

Find the measure of x in each figure.
Alex

Step-by-step explanation:

Because 2x and 40° are complementary angles.

\therefore \: (2x) \degree + 40 \degree = 90 \degree \\  \\  \therefore \: (2x) \degree  = 90 \degree  - 40 \degree \\  \\ \therefore \: (2x) \degree  = 50 \degree  \\  \\ \therefore \: 2x  = 50  \\  \\  \therefore \: x  =  \frac{50}{2}  \\  \\ \huge \red{ \boxed{ \therefore \: x  = 25}}
