Acompany that manufactures smartphones makes 70% of the phones with a touch screen and 55% of the phones with hd movie capability. 30% of the phones have both a touch screen and hd movie capability. what is the probability that a smartphone chosen at random has either a touch screen or hd movie capability?

19/20

47/50

13/20

43/50

17/20

Step-by-step explanation:

Let T represents the event of phones with a touch screen and H represents the event of phones with HD movie capability.

Given,

70% of the phones with a touch screen,

⇒ The probability of touch screen phone, P(T) = 70% = 0.7,

55% of the phones with HD movie capability,

⇒ The probability of HD movie capability phones, P(H) = 55 % = 5.5,

Also, 30% of the phones have both a touch screen and HD movie capability,

⇒ The probability of HD movie capability phones with touch screen,

P(H∩T) = 30 % = 0.3,

Hence, the probability that a smartphone chosen at random has either a touch screen or HD movie capability is,

First option is correct.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

circumference divided by 3.141592654 then timesthe radius twice
