Answer:
the probability of the dice is 1/6 and the probability of the spinner is 1/4.
Step-by-step explanation:
the probability of the dice=E/S=E=1 and S=6 because it is one dice. so P=1/6.
the probability of the spinner=E/S=E=1 and S=4 because the spinner is divided into 4. so P=1/4


so, the percentage of the rate is 0.185, what's that as a percentage? well, 0.185 * 100, 18.5%.
Answer:
perimeter of square=4×side
perimeter of square =4×13cm
