In a game, a participant is given three attempts to hit a ball. On each try, she either scores a hit, H, or a miss, M. The game
Sidana [21]

Answer:

chancing for wining is 54%.

Step-by-step explanation:

possible outcomes can be given as

HHH *

HHM *

HMH

MHH *

HMM

MHM

MMH

MMM

Out of those, only 3 will have the participant win the game:

HHH, HHM, MHH.

Probability (HHH) + Probability (HHM) + Probability (MHH)

since attempts are independant.

Probability (HHH) = 0.9 *0.4 *0.9 = 0.324

Probability (HHM) = 0.9 *0.4 *0.3 = 0.108

Probability (MHH) = 0.3 *0.4 *0.9 = 0.108

Add them up and get  = (0.324+ 0.108+0.108) = 0.54

hence, chancing for wining is 54%.

bellamy is building a gate to put on a fence. the gates measurements are 7 feet by 7 feet a diagonal wooden brace is going to be
Rama09 [41]

The length of the diagonal is the hypotenuse of the fence

The length of the wood is 7\sqrt{ 2 yards

<h3>How to determine the length of the wood?</h3>

The dimensions of the fence are:

7 ft by 7 ft

The length (L) of the diagonal is calculated using:

L = \sqrt{a^2 + b^2

This gives

L = \sqrt{7^2 + 7^2

Express as products

L = \sqrt{7^2 * 2

Express as radical

L = 7\sqrt{ 2

Hence, the length of the wood is 7\sqrt{ 2 yards
