plzzzzzzzz help Which statements about experimental probability are true? Select three options. Experimental probability has the
total number of trials in the numerator and the number of times an event occurs in the denominator. Experimental probability is the same as theoretical probability. An experiment to determine probability will include a number of trials. A probability experiment will count the number of times an event occurs. Experimental probability can be written in the form of a ratio.
=> An experiment to determine probability will include a number of trials. (it includes a number of trials. It is done multiple times having multiple trials.)
=> A probability experiment will count the number of times an event occurs. (Probability tells us how many times an event can occur.)
=> Experimental probability can be written in the form of a ratio. (Experimental Probability = )
We have to find the exact value of: arc cos ( sin ( π /6 ) ). We know that: sin ( π/6 ) = sin 30° = 1/2 Arc cos is the inverse function of cosine. arc cos ( 1/2 ) = 60° = π/3
