Cards numbered 1 through 30 are placed in a bag and shuffled. One card is chosen at random. What is the probability of randomly selecting a number less than or equal to 5, or a multiple of 7?
@tylermcmullen23
in the 30 cards, there are only 5 which are less than or equal to 5. so that would be put into the fraction: 1/6 how many multiples of 7 are n 30, do you think?
4
7, 14, 21,28
PLZ HURRY I NEED THIS TURNED IN IN 5 MIN
so thats 4/30, or 2/15. so i believe you add 2/15 to 1/6. gcf=60. so you have 8/60+ 10/60, or = 18/60. simplify to 3/10
Thats not one of the answers
what bout 1/45?
nope
@iGreen
if this isnt an answer, i give up.. 2/5?
give up then
sorry
do u think u could help me on one more?
i can try
.A game at a county fair has a spinning drum holding 15 colored plastic balls: some white, some green, and some red. Every time the drum spins, one ball drops out, its color is recorded, and then the ball is placed back in the drum. The table shows the results after 15, 150, and 1500 spins. What is the best estimate of the number of white balls in the drum? Outcome Number of trials 15 150 1500 white 5 61 680 green 9 74 713 red 1 15 107 A. 1 B. 4 C. 6 D. 7
wait for the first one, i think its 3/10
its not one of the answers though
