[Jawaban] Mariah is studying the life cycle of the monarch butterfly. She must choose one stage in the cycle to present in science class: egg, caterpillar, chrysalis, or adult. She plans to make her choice randomly using a custom spinner divided into four sections. First, however, she spins the spinner 50 times to see the frequencies it generates. | Stage | Times Landed On | | ----------- | --------------- | | egg | 10 | | caterpillar | 12 | | chrysalis | 15 | | adult | 13 | The relative frequency of landing on egg is $\square$. The relative frequency of landing on caterpillar is $\square$. The relative frequency of landing on chrysalis is $\square$. The relative frequency of landing on adult is $\square$. All the outcomes $\square$ be considered equally likely.
