Question

Dalia owns a gravel pit. She took a random sample of rocks and counted 58sedimentary rocks, 213 metamorphic rocks, and 522 igneous rocks. Use the observed frequencies to create a probability model for Dalia randomly selecting one rock from her gravel pit. Input your answers as fractions or as decimals rounded to the nearest hundredth.

Answer 1

Step-by-step explanation:

Given Dalia owns a gravel pit. She took a random sample of rocks and counted 58 sedimentary rocks, 213 metamorphic rocks, and 522 igneous rocks   Use the observed frequencies to create a probability model for Dalia randomly selecting one rock from her gravel pit. Input your answers as fractions or as decimals rounded to the nearest hundredth.

•  Given Dalia owns a gravel pit.
• According to the question total number of rocks Dalia owns will be
•        58 + 213 + 522 = 793
• Therefore out of 793 rocks, sedimentary rocks are 58, metamorphic rocks are 213 and 522 of them are igneous.
• Therefore probability of sedimentary rocks will be 58 / 793  = 0.07
• Probability of metamorphic rocks will be 213 / 793  = 0.26
• Probability of igneous rocks will be 522 / 793 = 0.65
